|
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 |

|
Again a new test with the beam on. At the begining the beam was off and it can be noticed.
There is a lead wall after F11 plastic and in the polyethilene block there are two lead bricks to block the beam to AIDA.

Thu May 30 06:41:18 2019, A. Algora, Background with the beam
|
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

|
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. |

AIDA plastic changed.
HV was at 1000 V, it was changed to 1300 V
Coarse gain was changed to x5, Fg remains as it was. |

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: |

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. |
