A. Algora | AIDA Plastik |
Nishimura san found the module used for the AIDA plastik in the last BRIKEN run. We put it instead of the TFA. It was kept in the same
setting conditions as in the earlier experiment.

Comments: AIDA in, sligthly less deeper than before. It is 17 mm less deeper. So from the other side we measure 17.7 mm to the nose of AIDa.
The source is on top of AIDA with a help of a plastic ruler, that it is lying on top of it. The other extreme of the ruler is attached with tape to the edge
of the frame on the beam side. The source is positioned on top of the detectors 3, and 4, in practical terms in the geometrical center, but on top of
AIDA. 60Co source from source box (key 3). No sources around, the sources are kept inside BELEN. |

A. Algora | Reference detector |
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.

A. Algora | Irradiation for 24Na |
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. |

A. Algora | F11 plastic connected |
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.

Coarse gain was changed to x5, Fg remains as it was.

A. Algora | Ref detector position changed, AIDA plastik HV changed |
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. |

There was an small increase in the counting rate of the detectors after the beam was delivered. The rate at
F7 was of the order of 5 kHz. But remember that there is a lead wall protecting the detector. Root file saved. Look at TSumA for example
