1. Target Lab. Update Chiranjib Dutta (UKY) Joe Katich (W&M) Xiaohui Zhan (MIT) Chiranjib Dutta (UKY) Joe Katich (W&M) Xiaohui Zhan (MIT) Transversity Collaboration Meeting Friday, May 4 th 2007

2. Works in our target lab. Oven/Support structure Optics Software The real tests

3. Oven / Support structure Installed the new oven earlier Installed the new heaters and RTDs UNFORTUNATELY, the structure was BROKEN near the bottom of the air flow tube GOOD NEWS===the oven is still safe and fine The new structure is being designed Waiting on it !! (within 4-6 weeks) Many thanks to Al and Susan

4. Optics New 5 to 1 combiners tested Found problems in a few and sent back to the vendor New 75 meter fibers (qty=10) tested Except couple of them, all look good ! All of them to be installed in the Hall in summer The Optics line design to be worked on shortly Simulation to be done shortly before that

5. Software Combine the spin-flip lab view code with NMR signal analysis and EPR measurement 1. NMR frequency sweep signal can be extracted and fitted after every spin-flip. Provide quick & continuous cell polarization monitoring. 2. EPR measurement can be controlled automatically by spin-flip program during every spin-flip, also can be controlled manually without affecting the main program. 3. Add counter connected to FG to monitor the frequency sweep process which is crucial to spin-flip. The reading rate from counter by lab view can be at 3-4Hz without interrupting the main spin-flip process. Spin polarization status(+/-) can be monitored continuously by a TTL output signal of the FG together with ADC and scalar. The record of Labview can communicate with EPICS as a complementary method to check the spin status All of the software programs will be fully tested after the installation

8. Real Tests The oven to be tested Laser alignment NMR/EPR/SPIN FLIP to be tested All the new related softwares to be tested accordingly Water field and frequency sweep to be tried New vertical coil to be tested in the new lab BB field mapping at some point (?)
