OVERVIEW


The high luminosity delivered by the Tevatron to the Silicon Microstrip Tracker poses risk of silicon damage and therefore the radiation dose must be limited to enable acquisition of meaningful physics data over the lifetime of the detector. For this purpose the D0 radiation monitoring and SMT safety system has been designed and built. The system continuously monitors the instantaneous and integrated dose received by the SMT and aborts the beam in case any of the preset limits is exceeded.
 

Further detail about the system can be found here.
 

Plots for the integrated radiation dose at the inner radius of the SMT for 2002, 2003 and 2004
 

Plots of radiation losses, organized by store, can be found here.
 

Instructions for the SMT shifter: please read here.
 

Details about BLMs and a lot of other information related to the Radiation Monitoring can be found on Ron Lipton's web page on D0 Radiation Protection References.
 

Details about how to modify the alarm and abort levels for the BLMs can be found on Modifying D0 BLM Alarm/Abort Levels.
 

Details on how to use the CGI web interface to see the FINGERS DATA can be found here.
