Comment: After irradiation of approximately 7 days, we extracted one Alu plate. It shows 24Na activity and also probably some beta+ activity.

The sample was not irradiated in the last 10 hours or so. It is positioned roughly in the center of the detector side in front of AIDA, using the frame prepared in Valencia.

It is not in the geometrical centre of the DTAS

Rates: 4.5 kHz (Dynodes), 4.5 (Anodes)  (Background level was at approximately 1.6-1.7 in both Dynodes, Anodes)

We need to check the alignment properly with Cs, but it looks that after one week some of the detectors have moved.

Group 1,3,5,7  (all seem to move with respect to detector 1)

Group 2,4,6,8 (detector 6 moved)

Group 11,13,15,17 (11 and 1 seem aligned, detector 13 moved)

Group 12, 14,16, 18 (12 and 2 not aligned, they seem aligned)

137Cs top and bottom test... to check differences we positiones the source at the top and bottom of AIDA respectively.

Furthermore, we have changed the LED rate. Source reference: Cs401 - 4763

For each detector (An & Dy), the peak is plotted when the source is at top & bottom (Attachment 1).

The cable of detector 8 was changed (long cable) to reduce the noise. The cable (long) of the reference detector was also changed.

For JL to play...

The beam stopped a couple of times due to problems before RRC

We have noticed that there is a problems in the coincidence Crystals-F11. The TAC shows a lot of counts. The
Crystals spectrum in coincidence with F11 do not. The time window of this coincidence is from-50 to 50 samples
and it should be from -180 to 300 samples to be centered in the peak of the TAC.

We will change it at soon as possible

The preparation directory was moved to /data/DRikenPreparation (from its first place /home/dacq/DRikenPreparation) because the lack of space.

New config file: 20190606_Conf.xlsx

Changed with respect to the earlier file (20190605_Conf.xlsx):

-The threshold of the Reference detector was changed from 2800 to 3500.
-A new gated histogram was added: ECryA gated by F11PLR in the energy range of the implanted ions, named as
EcryAGF11

Issue in AIDA PL (see screenshot). A lot of small signals; top, samples, bottom output of EFIR (picture taken
when integration = 50 samples; value in configuration = 20)

Setup: On 17th-May (11:18 - 11:38), AIDA was inside DTAS. Measurement of 60Co source.

There is an effect if the pulser is at higher frequency in the low energy part of the anodes (apart from the funny situation that the scaler shows an increase from 1.7 Khz to 8.5 kHz and the dynodes rate remain with the same rate)

The effect can be seen in the spectrum of the anodes. See screenshots in the attachment. First attachment (pulser at 10 Hz, second attachment pulser at 100 Hz)

Small alignment corrections were needed, of the order of 0.5-1V.

Rate of Dynode 5, 15, 17  seem a little higher than the others. The same for Anode 11, 15, 17

Not clear why the Dynodes rate is so high compared with the anodes. There is not such a big

difference in rate of the individual detectors.  

(Dynodes and Anodes rates are taken from the Python script written by Jorge, that correspond to the full card)

Later it become evident that probably we need to increase  the threshold of detector 8 again (Dy08).

Before it was not like that, but now seems to be triggering in the noise.

T spectra for AIDAPL and F11PLL and F11PLR are defined from now on. The ancilliary card was not saving the CFD values for all channels.

It was modified in order to have those spectra. A new configuration file will be saved. See in the attachment

Synchronization with AIDA is working, see attached document to proceed.

Following the instructions of CAEN, the SY2527 is working again. Some pushing, massaging appear to solve the situation

Again the Reference detector was firing mainly in the noise. Threshold increased to 5000 !!!!

New config file was saved, rate of Ref detector now: aprox. 400 kHz

The reference detector was very noisy. The threshold has been changed from 2000 to 3200. We should look at this more carefully.

The position of the fiber was also changed. It moved too close to the Cs peak. Probably it has to do with the flexibility of the plastik screw that fixes it.

The position of the reference detector in the ancilliary card was changed from channel 10 to channel 9. Remember that this is important

in relation to all files saved until now.

The HV of AIDA plastic was changed from 1300 V back to 1000 V.

A new configuration file provided by Alvaro and Jose, with some small changes will be loaded.

cp 20190529_Conf_ATJLT.xlsx 20190530_Conf.xlsx

The new configuration file has been uploaded. Reference detector appears in channel V2A8C9. It was necessary to change the range of the histogram, and to recalibrate it.

With the new configuration parameters the pulser appears at 1360 keV in the calibrated spectra of the reference detector.

The threshold of the Ref detector has also been changed. From 4400 to 2800.

New configuration file after a few small changes in thresholds.

The E range of the AIDA plastic for the construction of the TAIDA plastic spectrum has been changed. Also the range of the TAC_AIDAPL_CryA has been changed.

The estimated range of AIDA was based on the file 201906011624_background_AIDA_in.root, which was with no beam. But I am not sure is the calibration of 

AIDAPL is fine.

A file with Co and Cs was collected for 10 min

201905201444_137Cs60Co_align.root

after a minimal correction of the voltages (mentioned in the earlier entry). After this a new calibration was performed.

Rates per detector of the order of 1.7 kHz, Ref det rate 63 Hz, with the pulser set to 10 Hz

Now a  check on the other available sources will be performed.

Until now the used Co source was CO401(2530) , which is rather strong (corresponds to key 6)

and the Cs source was CS401 (4763) (key 8). This Cs is fine.

Now the sources on the red box (color ?) will be explored.

Configuration file: 20190520_Conf.xlsx

A new config file provided by Jose and Alvaro is loaded

cp 20190531_Conf_JLTAT.xlsx 20190531_Conf_2.xlsx

Comments: I have modified it afterwards to have TAIDAPL, the threshold in E was too high. The TAC_F11R_CryA was also modified. It is shifted in time and cut as it was.

It remains cut.

*Update*: some of the histograms saved from DACQ online are duplicated (same name, but different cycles: ";1" and ";2"), and the second copy is empty. When you open the ROOT file and write the name of the histogram, the last copy ("cycle") is called, so the empty histogram is displayed.

Several changes and corrections
Naming: V2A8C1 -> Aux01, ...

New or corrected
Aux13 -> LP_out (puse out of light pulser)
Aux15 -> DTpulser (Out of GSI clock triggering LP)
Aux16 -> SyncPulser (Out of GSI clock send out for synchronization with AIDA & BigRIPS)

Ranges changed
Aux09, ERefAn

We observed that LP_out was counting less than the other two
so we tried to check DACQ parameters. We basically change nothing
Only activated "CFD time"
Note that pulse out is a very strange signal:
Negative(?),-400mV offset, 200mV high
In the DACQ is treated as positive signal with a large negative offset.

With the help of Tom the additional lead pieces were put. So now the hole in the lead shielding matches the hole in the polyethylene shielding.

The hole is 11 cm x 11 cm approximately

The aluminium plate of 3 cm thickness arrived and the lead shielding was dismounted and mounted again. We left a narrower hole in it.

Special thanks to Tom, who helped with the hard physical work.

Irradiation of two pieces of aluminium of 80 mm x 40 mm x 10 mm will be performed at the second BigRips dipole.

The pieces were placed with the help of Fukuda and Nishimura san.

We have corrected small gain changes by changing the HV of detectors. Attached are the new values

F11 plastic has been connected to our dacq as it was in the earlier BRIKEN setting.

The detector cables were followed and connections checked.

The outputs of the detector (L and R) go through an Ortec TFA 474 with the following settings:

Coarse gain: x4

Fine gain: looks minimal

Integrate (ns): 200

Diff (ns): 100

Non-inv setting

After the TFA, the Right signal is plugged in channel 1 of our card, and an attenuated signal (50 Ohm) is

plugged in channel 3. Similarly the Left signal after the TFA is plugged in channel 2 and the attenuated 

signal is plugged in channel 4.

Parameters of the channels of the dacq have to be checked.

Dynode 08 threshold was changed from 675 to 790. Now the rate in this detector is fine.

The global rates for the cards (dynodes and anodes) are similar.

Det 3 moved, both Anode and Dynode. So we have changed the HV cable to test if there are no more jumps. We used cable 9 and it was not

relabeled. The HV of the detector was corrected. It was changed to 527.5 V

Signal cables (long cables, from preamp to digitizer) of channels 13 and 16 were changed. For the moment they have not been relabelled.

We assumed that it was not a HV supply or cable problem, since the anods were aligned and only the dynodes moved.

After changing the cables we realigned the dynodes and recalibrated all signals. Screen shots are attached.

After checking the shifts in gain, it seems that for most of the detectors the dynode and anode signal moved in the same direction with the exception of detector 13 (dynode and anode do not move

equally, so probably there is a cable problem here, probably in the Dynode 13 or preamp problem)

We have been running with Co and Cs for the weekend to check the overall stability.

Seems that the detectors did not move too much. Please note that the Ref detector was plugged incorrectly in channel 8

instead of channel 10 of the ancilliary card.  A new run will be done to include the reference detector.

It looks that the calibration might be sligthly shifted for detectors 12, 13,17 (Dynodes)

Comment: At the begining there was no beam, to see the difference. The lead bricks blocking the way to AIDA has been removed as well as the

polyethylene blocks. The lead wall after F11 plastic remains, and of course the lead shielding and the polyethylene shielding before the DTAS is not removed.

Only the blocks that were inside the holes were removed.

Beam arrived around 17:47, intensity at F7 is 3.3 kHz, at F11 of the order of 2.4 kHz, at Aida plastic of the order of 2 kHz after substracting. The beam is centered at 102Sn, but there are a lot of other staff comming through

the noise level.

The increase in the counting rate of the NaI is very small.

I will not erase it and continue to collect root files (no lmd for the moment), they are still optimizing things. Rate at F11 should be similar to

Comment; seems dynode 4 moved a little up. Most detectors keep a reasonable alignment

Comments: AIDA out. The source is positioned 5 mm deeper than before from the holder side (the arm is 5 mm longer).

To check if the assymetry is reduced.

Comment: Aida in, source in the position as in the earlier entries. Just to check if there is any jump. No lmd, only root.

No large displacements. Det Dyn1 seems to have slightly larger statistics. The assymetry of the two sides is clear, as it should be.

Comments: Aida out, source in the center. As in earlier measurements 5 mm deeper.

Reference detector might require repositioning of the optical fiber. It appears too close to the Cs peak and it is very noisy.

Start: 14:32

Stop: 14:37

Source: 137Cs

Comments: Detectors show small drifts, of the order of the precision of the HV (we could apply 0.5 V corrections to align some of them, but I will not touch them now)

Dy16 looks quite off in the background measurement, but not with the Cs one !!!.

Calibrated spectra: Dy3 an An3 moved a little in the same direction, An12 looks also a little displaced.

Now I plan to measure some sources with AIDA in. It means that the sources will not be centered. The available distance from the oposite side to

the nose of AIDA is 16 cm.

137Cs source in the center of the DTAS, with the IFIC holder

Comments: 137Cs source with AIDA in, Source CS401, 4763. The source is not centered. It is positioned (the center of the source) at 14.6 cm

from the beam side external edge of the frame (lower NaI numbers). The holder is touching the nose of AIDA.

The nose of AIDA is 16 cm from the external edge of the frame (down stream). In that position Si # 3 is at the center of the DTAS according to Tom.

We have to be very careful when AIDA is moved in. Some of the AIDA  flat connector cables are touching the connectors of our NaI cables.

Individual rates (kHz), remember the source is not at the center, so we expect assymetry in the counting rates):

The Ba source of the red box is too strong. We can not use it. I need to identify the other one, which does not appear to be in RIBF.

The counting rate was 74 kHz in the DTAS.
