Status of ST 1 • • Peyrej @ ipno. in 2 p 3. fr • 9 tracking Quadrants (Q 1 to Q 9) of ST 1 are now constructed till end of March Gain homogeneity, Gas leakage, Mechanical tension on wires and Dark current are within defined standards Only on one quadrant (Q 2), mean mechanical tension on wires is two high (70 g instead of 60 g). About 2 wires are breaking per 6 months. The wires have to be changed and stretched at nominal tension of 60 g IPNO-RDD-Jean Peyré 3 Badesi - Sardinia - May 2006

Special requirements for ST 2 Peyrej @ ipno. in 2 p 3. fr From 2 nd to 12 th of may, our colleagues from SINP came to Orsay to test the mounting of ST 2. Here are our main commun conclusions: 1. Special care must be taken to verify the size of real chambers 2. SINP has to study and construct the tools for lifting quadrants of ST 2 3. Low Voltage Bus Bars are in contact with metallic supports and plateform of alignment systems. SINP has in charge the modification of the bus bars to avoid those problems 4. SINP has in charge the connection of gas tubes to the general gas system IPNO-RDD-Jean Peyré 33 Badesi - Sardinia - May 2006
