Notes
As recorded by Mark:
- Steve suggests welded hydrogen line connections rather than fittings, fittings developed leaks over time.
- Concern from Dave: distance of the condenser from the cold head. Jim moved it downstream to reduce volume of hydrogen in feed line.
- Dave suggests larger surface contact for making the thermal short between hydrogen line and shield.
- Hall B used boil-off helium to pre-cool target gas. We may add pre-cooler from higher temp head.
- Dave suggested connecting the heater directly to the condenser, not the conduction tube.
- Dave recommends high quality temperature and pressure instrumentation, well calibrated. Useful in knowing when the target is full by knowing position in the phase diagram.
- Dave made had some comments on how to optimize the arrangement of the feed and return lines.
