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.

201905301457_background_AIDA_in.root (beam was stopped for a short period)

Rates with the beam: 2.2 kHz (Dynodes), 2.3 (anodes)

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

the rate at F7 according to Pieter. Rate at F7 plastik  is 5 kHz. The plastik spectra (F11, our plastik) shows some spikes.

LED in EDy16 looks wider

The TACS were recovered. Probably all the files of today (until now) and generated after the configuration file change do not have the calibrated spectra.

Comments:

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

Comments:

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.

Short root file is attached as example

*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.

$ root -l 201905312230_background_AIDA_in.root

Attaching file 201905312230_background_AIDA_in.root as _file0...
(TFile *) 0x238ac70
root [1] ESumA->Draw() //empty!

So, there are two options: delete the second copy of the histograms, or create a newer copy of the filled histograms. In order to perform the second option, please write this line,

$ root -l 201905312230_background_AIDA_in.root
root [0]
Attaching file 201905312230_background_AIDA_in.root as _file0...

root [1]  for (auto&& keyAsObj : *(_file0->GetListOfKeys())){auto key = (TKey*) keyAsObj; if( 1 == key->GetCycle())_file0->Get(Form("%s;%d",key->GetName(),1))->Clone(Form("%s;%d",key->GetName(),3));  }

root [2] ESumA->Draw() //copy of ESumA;1!

The changes will not persist unless the file is opened with "update" mode and the changes are saved at the end.

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.

Rates with NO BEAM: Dynodes 1.6 kHz, Anodes 1.9 kHz

Rates with BEAM: Dynodes 1.7 kHz, Anodes 1.9 kHz

File with guaranted no beam saved at 17:20 (201906011720_background_AIDA_in.root)

Another one saved at 17:29 (201906011729_background_AIDA_in.root), no beam also, still waiting, similarly saved at 17:41

Attachment 7 shows the rates of TF11PL (black), TCryA (blue), and TAIDAPL (the other color ?). it shows the "noise" level of the AIDA PL, and the increase in the counting

rate of the crystals.

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.
