DESCRIPTION
T979 (~10) Picosec timing: LBQ = L-bar Quartz Cherenkov radiator 30mm and 40 mm bars, each 3mm x 3mm. Light up light guide bars to Hamamatsu SiPMs MPPC S10943.(Sergey Los). SiPMs. p (120 GeV ). 2 boxes like this, so 4-in-line bars at at time. 2mm x 2mm trigger counter. PMT240 - PowerPoint PPT Presentation

p (120 GeV)
SiPMs
2 boxes like this, so 4-in-linebars at at time
2mm x 2mm trigger counter PMT240MCP, ref timeTwo L-Bar Quartic boxes
Beam, 120 GeV p
Beam deliberately through light guide bars
Scope traces (5 GHz, 200ps/pt)3 bars with PMT240 (bottom)2 ns/div & 20mV/div
Without clipping CapacitanceWith clipping CapacitanceRise times < 1 ns, good.
Successful runs, data being analysed. Await resolutions.
