2MC Friday Meeting 20 Oct 2006
OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY
Initial Water Testing Setup
A primary containment has been mocked up to allow initial water tests to be performed
Will be used to debug Labview control software and test some of the sensors
Remainder of syringe hardware scheduled for delivery week of Oct 23

4MC Friday Meeting 20 Oct 2006
OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY
Syringe Pump Performance Testing
Control system development complete based on water tests Minor modifications may be required after switch to Hg, but none are
expected Data logging incorporated
System can produce a 20m/s, 1cm-dia water jet Water test nozzle configuration approximately matches one of the two Hg
nozzles My opinion: jet quality looks good for a no-field condition. Holds together for
better than ~1/2m

OAK RIDGE NATIONAL LABORATORYU. S. DEPARTMENT OF ENERGY
Load Testing of Common Baseplate & Target Cart
CERN Safety Commission voiced concerns regarding analysis performed on common baseplate design
Load test performed on structures to verify strength and test adjusting mechanisms
Estimated component weights Magnet: 12000 lbs (5440 kg) Hg system (with 23liters Hg): 4000 lbs (1810 kg)
Test weights Magnet: 13600 lbs (6170 kg) = 113% estimated weight Hg system: 4500 lbs (2040 kg) = 113% estimated weight

Conclusions
Syringe pump control system development completed
System can produce 20m/s water jet within pump's performance limits No reason to think Hg will be different
MERIT common baseplate has been successfully tested with 113% expected loading
Final assembly and optics integration to commence shortly
Switch to Hg will be made once all operational aspects of system have been tested with water

Hydraulic system fill and drain procedures developed
Hg control system wiring is underway, water tests to start afterwards
Ready for Hg testing after conclusion of water tests and when remainder of fabricated components available
