No
The clock is in 10 ns intervals
So 5 => 50ns
The trigger is Fast NIM standard. Talk to Tom
With such a short time ,a lower limit of 1 and high rate discriminators the Trigger will appear true all the time. |

Patrick Coleman-Smith | Clue to difference between ASICs 1&2 and 3&4 | While investigating a VHDL conundrum I have noticed that the Mux ADC serial readout clock has a 'FAST' slew rate on ASICs 1&2 and a normal slew rate on ASICs 3&4.
Is it possible that the higher slew rate is actually better filtered by the ASIC de-coupling etc than the slower one.
Unfortunately I can't try this out yet as the "conundrum" means the VHDL version isn't good enough just yet.
Hopefully today.....

DK, TD, JA | Clock settings at the waveform generator stage | Clock settings for this experiment are slightly different than in the previous case.
Below are strictly the settings for the waveform generator itself.
Sent to AIDA side: 0 to 5 V amplitude, 50 MHz frequency
Sent to BRIKEN side: 0 to 5 V amplitude, 25 MHz frequency
Thus, both teams are taking TTL-type signals. However, the BRIKEN one goes to the Philips module which essentially converts it straight away to NIM.
There may have been a slight misunderstanding yesterday about the setup, but finally the waveform signal going to BRIKEN was checked and there was no problem. So we don't make
any changes (e.g. changing the waveform generator to a NIM-type output). |

Patrick Coleman-Smith | Changes to AIDA software | An updated copy of the merger has been downloaded ( merger64.AD ) with a copy of /MIDAS/Merger/AIDA/Startup.
These two enable the output of all of the SYNC data items to the TapeServer.
The System Wide Checks browser window has been updated and includes a report of the number SYNC pulses sent by the Master timestamp module and the number of SYNC pulses received by the Slave modules. These should all be the same value.
The ASIC4 browser window has been updated to add two actions to the Experts only menu. "Disable all ASICs For Readout" and "Enable all ASICs for Readout". These two are useful when starting a noisy system. The sequence would be to start the Merger, toggle Pause. Then start the DAQ ( FEE64s ). "Disable all ASICs For Readout" then in the Merger toggle Pause. I found this made starting the merging much more successful. Then "Enable all ASICs for Readout" to run. I shall add similar actions to the Discriminators but will ensure the Mask Patterns set by the Restore are maintained and restored by the "Enable" action.
Before adding this capability it was quite hard to tune the system to guarantee the Merger a full set of SYNC data items at any one time. I have been running the FEE64s with low thresholds, detectors and no HV.

CB | Card test | I tested the FWHM of a BNC PB-5 pulser signal as a function of shaping time using the first produced ISOL FEE64 card in Daresbury Labs.
Find attached four representative spectra per ASIC taken with 8, 5 and 0.5 us shaping time values. Run times are different.
Also find attached a plot of the FWHM as a function of the shaping time for the first channel in each ASIC. There appears to be a maximum of the FWHM at around 4 us. This may indicate the main source of noise is external, and at ~4 us the band pass lets most of the noise in.
Unlike the FEE cards employed in RIKEN, this card is grounded to the metal base plate through the screws. In order to investigate the effect of this ground on the noise level of the ADCs in the card, the card was disconnected from the metal plate base. An additional layer of insuating material was placed between the base and the FEE64 card. Nylon screws rather than metal screws were employed to affix the card to the base, and the same tests as before were repeated. See plot below. Overall, the same trend is recovered but suprisingly the FWHM is larger than before for ASICs #1,2 and #3. ASIC #4 has a lower FWHM than before. The reason for the change is not obvious, and may need further investigation.

TD, Updated Patrick | CAEN N1419 HV output common mode noise |
There appears to be significant common mode noise on the output of the
CAEN N1419 4 Ch Reversible 500 V/200 ľA NIM HV Power Supply Module (USB)
- the specification quotes 'Max Ripple smaller than < 5mVpp'. We configure
the CAEN N1419 outputs as floating wrt NIM module/crate chassis.
For example, attachment 1, shows the output of module #2 (Addr 01) channel #3
(unused channel) set to 10V (leakage current 0.030uA) - core (Ch 1)/braid (Ch 2).
Tektronix 3034C channels 1 & 2 are both set ac/1M.
Attachment 2 shows math function Ch 1 - Ch 2 (50mV/division cf. 200mV/division
for Ch 1 and Ch 2)
Attachment 3 shows CAEN N1419 #2 settings
Attachment 4 per attachments 1 & 2 *except* the cables from channels 0 and 1
of CAEN N1419 #2 have been disconnected from the NIM module. The structure of
the common mode noise changes but its amplitude remains significant. This
presumably indicates that there are other sources of common mode noise in
addition to that observed at the output of the CAEN N1419 HV outputs.
Attachments 5 & 6 show the NIM crate front panel +6V output wrt ground
for the lower (NIM Bin type REPIC, BNC PB-4, Ortec 433, 2x MACB, 2x CAEN N1419,
1x CAEN 1419B) and upper (NIM Bin type OKEN, 9x MACB) AIDA NIM bins respectively.
All +/-24V, +/-12V and +/-6V front panel outputs show the same noise structure.
Attachment 7 shows equivalent of attachment 6 but using Tektronix DPO3054
which can display FFT.
Update -----------------------------------------
Tested the CAEN HV supply in T9 using the same method and observed similar results.
With help from Mos Kogimtzis a better method of measuring the HV noise was used.
The co-ax from the isolated output of the HV module was connected to one input of the 'scope. HV set to 1V.
Thus the screen of the HV signal is grounded at the 'scope amplifier input. This nearer to how the HV is used with a detector.
The single signal input channel was set to DC 1MR with an offset of 1V.
The 'scope can now display at 4mV/division.
The peak/peak was less than 5mV.See attachment 8 slide 1
There are features at both high and low frequency, attachments slides 2 and 3. NB 1mV/division.
If a differential measurement is required then a suitable cable with a shielded twisted pair is needed.
Update #2 -----------------------------------------
Moved the AIDA T9 HV supply to a CAEN NIM bin. Newly purchased this year.
This is the only module in the bin.
Used the simple method of noise measuring as before with the same cables and 'scope.
Attachment 9 shows there is a different type of noise. Not regular like attachment 8 but more random and larger.
The HV is set to 1V.
Further investigation will be carried out using AC coupling and HV set to 50V. |

OH | BigRIPS particle ID | I've been going through collecting the BigRIPS root files with Phong and making sure they are on AIDAs1.
The files we have for NP1306 are not the standard format so to get particle ID you need to do this command taken
from the RIKEN elog.
Command to construct the PID in the merged files from preliminary data:
Example file a11111_b1181_e_1130_ion.root
tree->Draw("(F11ICADC[0]+F11ICADC[1]+F11ICADC[2]+F11ICADC[3]+F11ICADC[4]+F11ICADC[5])/6:F11Pla_TM-F3Pla_TM+F5X*0.0383261>>h(500,0,25,500,0,16000)","","colz");
Though these root files were not created by the BigRIPS team so can be cleaned up further but should be good
enough for initial analysis. |
