Comments:  For a short period lmd file will be collected as well, to have correlations in case it is needed. Rate at F7 4 kHz

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

Comments: they stopped the beam to put the target in

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.

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.
