The lead bricks blocking the way to AIDA has been removed as well as the</p> <p>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.</p> <p>Only the blocks that were inside the holes were removed.</p> <p>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</p> <p>the noise level.</p> <p>The increase in the counting rate of the NaI is very small.</p> <p>Rates with NO BEAM: Dynodes 1.6 kHz, Anodes 1.9 kHz</p> <p>Rates with BEAM: Dynodes 1.7 kHz, Anodes 1.9 kHz</p> <p>File with guaranted no beam saved at 17:20 (201906011720_background_AIDA_in.root)</p> <p>Another one saved at 17:29 (201906011729_background_AIDA_in.root), no beam also, still waiting, similarly saved at 17:41</p> <p>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</p> <p>rate of the crystals.</p> <p> </p></td> </tr> </tbody> </table> </p><p> </p>
