Presentation Transcript

  1. RF noise measurements week of 1-6 September 2003 measurements at the Linac3 200MHz, 350kW cavity ~1.5m TPGino amplifier • RF pickup on the chamber • Study grounding techniques • RF pickup when chamber is on HV • Comparison of ionization signal in • RF On and RF Off mode. ~1.5m ~2m cavity

  2. X-ray background measurements Expose the detector to radioactive sources corresponding to the Photon spectrum taken at LAbG, e.g. Fe55: 5.9keV Mn54: 5.5keV and 800keV Co60: 1.3MeV and 1.17MeV Cross-check the measurements with simulations (Geant4) Will be done by end of October 2003 both with the TPGino in Neapel and also with the TPG at CERN
