SSD LS1 activities ITS Operation Meeting 28/02/2013
LS1 Activities: Summary • Cooling: see Claudio presentation • PowerSuppliesIntervention • FEROM Investigation • DDL/LDC missingdynamichandling
PowerSuppliesIntervention • Low voltage: modificationtodecrease the common mode oscillation • 17 PS replacedduring 2012 TS • Remaining 127 PS tobemodifiedduring LS1 Who: Massimo + Ton fordismount and re-mount Time estimate: • ~ 1 week todismount and bringto the surface (March ALICE week by me and Ton) • then sent to CAEN formodification (20/30 per month back) • then 2-3 monthsintegratedto test in lab and installthemagain Resourcesneeded: • DAQ and DCS neededto the finaltests
FEROM Investigation • Check on the correlation between radiation level (and integrated dose) and the problems on our FEROMs • If needed, taking into account the higher radiation level in the Run 2, replacement/upgrade of the whole FEROM system • TBC Who: Massimo (Investigation) Expected time: ~ 1 week to complete the investigation + no time estimate for the intervention if any
DDL/LDC missing dynamic handling • Who: no people available at the moment • Time estimante: no time estimate
