RMon #8 for 7/10..3.11/08 floor positioni.e. from installation of equip. to end of beam Integrated beam intensity 6.43 1018 pot Transient effect caused by moving average D.Kramer TS-LEA
RMon #8 for 7..23/10/08 floor positionfitted Hadron fluence vs. Beam intensity Integrated beam intensity 3.379 1018 pot D.Kramer TS-LEA-RAD
RMon #7 working fine after position change, but… D.Kramer TS-LEA-RAD
A power cut in the test station occurred after ~2h of beam D.Kramer TS-LEA-RAD
RMon #7 power cut after ~2h of beam • 1st Beam after placement of electronics started • 10:45 on 9 Oct 2008 • Power off for Rmon#7 (caused by PConv rack) • 12:58 on 9 Oct 2008 • Integrated beam intensity = 2.01 1016 pot • Hadron fluence unavailable since due to HW problem D.Kramer TS-LEA-RAD
RMon #7 power cut after ~2h of beam D.Kramer TS-LEA-RAD
RMon #7 for 23/10..3/11/08 floor position Medium sensitivity Dose requires linearization Integrated beam intensity 3.047 1018 pot D.Kramer TS-LEA
Combined results for the 5 RadMon positions normalized to 1018protons on target PRELIMINARY comparison with FLUKA data; High gradients, geometry details (corners, empty ducts) and statistics produce uncertainties of factor ~2 Generally higher Fluka values than measurements as seen with PMI comparisons (see talk of A.Ferrari in SBWG) D.Kramer TS-LEA-RAD
