1 First Assembled Rod in US
First rod in US fully assembled Took approximately 2 hours for assembly Electrical tests have just begun

2 Vacuum Rod Assembly Tools

3 Single Rod Test Stand at UCSB
Complete set of electronic ready to test single rods Test box provides dry, dark, and electrical isolated environment Connects to Rod burn-in chiller for cooling First production rod tested in stand (J. Lamb & P. Gartung)

4 Rod Testing Results Faults clearly seen in rod using new LT
Only opens on rod so far Laser gain differences add complication to data analysis Fixed noise cuts will NOT work due to 50% variation in laser gain Hopefully laser gain can be measured by header height Similar work on optimization of calculation of pulse height & peak time variable needed as in module LT See P. Gartung’s talk More statistics needed in order to know how best to test rod ARCS Rod LT

5 US Multi-Rod LT Stands Physically four basic components: Chiller Rack
Freezer Cables

6 Multi-Rod Stand: Freezer Control Box
RH and T sensors PS -12,+5,+12 Flowmeters Valves control Proximity detectors

7 Multi-Rod stand : Software
PC guides the user on the Rod setup. Button “Prepare to Load Rods.” Rods loaded. Prepare to burn in. Ready. Start burn in. (Interlock software pops up) Burn in finished. Drain Rods. Rods drained. Proceed to disconnected them. Interlock Logic: Cooling interlock Stop coolant supply Dew point (TFer Coldest Point ) Freezer open Dry Air Flow Power interlock Kill LV+HV TROD Hottest Point (Limits) Flow (each Rod and total) Chiller status Freezer status

8 Multi-Rod stand :Interlocks
Overall Status The FNAL stand hardware and software are completed. Have cloned most parts for UCSB. Installation in progress this week
