<p>Again a new test with the beam on. At the begining the beam was off and it can be noticed.</p>
<p>There is a lead wall after F11 plastic and in the polyethilene block there are two lead bricks to block the beam to AIDA.</p>
<p>201905301448_background_AIDA_in.root</p>
<p>201905301457_background_AIDA_in.root (beam was stopped for a short period)</p>
<p>Rates with the beam: 2.2 kHz (Dynodes), 2.3 (anodes)</p>
<p> </p>
<p> </p>
<p>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</p>
<p>the rate at F7 according to Pieter. Rate at F7 plastik is 5 kHz. The plastik spectra (F11, our plastik) shows some spikes.</p> |
