Fully reconfigure VULCAN for fluorescence measurements Anna cooling system and SiPM holder ready
Test if signal from S13360-6050-PE is good with current VULCAN read-out board - if not, work with ET to design new circuit - also use Hamamatsu board and compare Anna/Joost
Test how signal from S13360-6050PE degrades when connected over a long cable as will be the case in XAMS - decide if we need pre-amplifier inside XAMS - together with ET Noor/Joost
Procure SiPM read-out board - 4+ channels, S13360-6050PE/CS SiPMs - from ET, possibly a total of 4 or so if economic Anna/Joost Previous SiPM test results
Install and test 16-channel digitiser for XAMS AP/Maricke XAMS test run finished?
Set up XAMS to start a run Tobias
Measure rest-gas composition in XAMS Noor
Measure outgassing from PTFE Noor
Re-design the guts of XAMS to include SiPM readout of a possible fluorescence signal (new PTFE sleeve). Ask advice from Marieke and from Oscar (from MT). Come up with a proposal. Joost/Noor
Task - software/analysis DRI Dependencies Status
XAMS MC - simulate calibration sources, g1 expectation AP/?
VULCAN MC - simulate photon paths/coverage fraction of SiPMs Anna
Based on XENON1T/nT data, calculate possible PTFE fluorescence efficiencies and compare to sensitivity achievable in VULCAN Pranati
Analyse data from XAMS. Ask Carlo for help
Analyse data from VULCAN. Ask Marjolein for help
