1. 1 04/25/06 TRR Update 8-ID Recent Activity 8-ID General New resident post-doc –Martin Tolkiehn »Started 4/10/2006 »Sharing office with Xuefa Li »X-Ray Standing Waves and Wave- Guide experiments »Supporting some 8-ID-E and 8-ID- ”G” experiments Interesting experiments in recent weeks: –8-ID-E »Super-solid He »Cr CDW XPCS

2. 2 04/25/06 TRR Update

3. 3 –Plan to replace E monochromator exit window and crystal holder during shutdown Eliminate D-E air path Allow eventual removal of 8-ID-A Be window –GISAXS vacuum-chamber-to-flight- path connections being modified to eliminate sample motion arising from bellows vacuum-loading –E set-up (Si(220)---microdiffraction) will be enhanced: Channel-cut crystal to reduce harmonic contamination Simple fluorescence set-up (to minimize use of 1-BM) Microdiffraction and zone-plate-based XPCS 8-ID-E & G Recent and Upcoming Activities

4. 4 04/25/06 TRR Update –Installation and initial testing of the new pseudo channel-cut monochromator for 8-ID-I has been completed Team effort: Suresh (and Michael and Alec), deming Shu, Harold, AES-MOM, AES-MED, AES-SI and AES-BCDA Some scary moments over the past few weeks: –Χ-motion yoke on 2 nd crystal blocked line of sight to 1 st crystal –Partial vent after installation at the end of the beamline---thought we had broken a Be window; tested Jeff Alicz’s new procedure for suspect Be contamination clean-up Ge(111)-monochromatized beam was found only a few hours after first opening the shutter!! 8-ID-I Recent and Upcoming Activities

5. 5 04/25/06 TRR Update 8-ID-I Recent and Upcoming Activities –Piezo and picomotor fine pitch adjustment of Χ and θ of second crystal via flexure pivots –UHV linear-stage-driven rotation of 2-crystal (Ge(111) assembly –Ethernet and serial controls via EPICS 3.14
