Workday@YaleISR Testing Questions
In this testing session, stakeholders review the testing approaches for integrations and the People Hub, syncing environments, system owner readiness, and discuss various scenarios and roles for defect management. The ISR test roles and responsibilities are outlined, emphasizing the importance of coordination and communication among different parties involved in the testing process.

OCTOBER TESTBEAM AT THE H8 BEAMLINE This Test beam was realized inside the North Area of CERN, precisely at the H8 beamline. The H8 beam is a secondary particle beam that provides hadrons, electrons or muons of energies between 10 and 400 GeV/c, as well as 450 GeV/c (primary) protons and up to 400 GeV/c per charge primary Pb ions. Only the muon beam was used for this test. Measurement realized: a) BIS78 Final prototype overall test The aim of this test was to ensure that the whole prototype was working correctly b) Parameters phase space scans The aim of these scans is to find out all the possible electronics working points and their properties LUCA PIZZIMENTO 3
TEST BEAM AT H8 EXPERIMENTAL SETUP The BIS78 Final Prototype is composed by 3 mono-gap equipped with both the analogic and the digital FE. The gas gap is 1 mm thick and the electrodes are 1.2 mm thick each. The mixture used was 95% TFE, 4.7% I-C4H10, 0.3% SF6. X,Y ReadOut Strips Gas gap Scintillators The trigger system was composed by two scintillators of around 10cm x 10cm. The data acquisition was realized by using a CAEN TDC. The low voltage system was realized in such a way to have the possibilities to regulate each parameter individually, allowing a deep parameters regulation for each FE board. The FE board low voltages studied: 1. Pull Up & Discriminator The stability of the system 2. Threshold & Amplifier The effective threshold applied on the signals Muon beam LUCA PIZZIMENTO 4 Bis78 Module-0
