The T2-MK2 target was transferred from the storage pit to the beam line yesterday (April 16th). The field was measured to be approximately 165mSv/hr at 0.5m from the target ladder (after approximately 5 months of cool down time). Vacuum was started this morning and has pumped down normally (1ACG4 at 11mTorr after ~5 hours) indicating that the target is leak tight.
The T2 profile monitor and protect monitor were 'blip' tested by Bill Rawnsley and Mike Russel from the racks on the Meson Hall mezzanine today. The response from both monitors appeared normal.
T2 profile monitor and M20 beam blocker actuation were tested from the MCR, both devices actuated smoothly and all limit switches registered properly.
The T2 target is now ready for beam and the T2 monolith may be covered. |
