Phobos Management Structure

Institutional Responsibilities

PHOBOS PROJECT IS IN GOOD SHAPE –we did follow your recommendations to consider changing the electronics and using one arm as contingency –electronics and DAQ have been redesigned –with only one arm, we have a contingency of 21% of uncommitted costs –we plan to use any unspent contingency towards completion of 2nd arm PHOBOS WILL BE READY ON DAY-1 FOR PHYSICS –everything will be in place except for a completed second arm DURING COMMISSIONING PERIOD WE PLAN –to have in place the trigger counters, DAQ, parts of multiplicity and vertex detectors, and parts of the TOF –to commission all aspects of PHOBOS, study backgrounds and triggering, and obtain a preliminary measurement of dN/d 
