It was reported on 2/27/2012 that the XRD had a very high noise/background. For several tests, the results remain the same. The results were sent to Bruker engineer. Waiting for response.

Bruker engineer worked on this XRD for two days. The XRD is now aligned well. I did several tests and concluded that the XRD worked well. You may use it now.
Please do not touch beam side and detector side. It would be very time-consuming and costly to align the old style XRD.
UCI purchase office generated a PO on 3/8/2012 and sent it to Bruker in the afternoon. Contact Bruker engineer immediately to schedule a service. Bruker service engineer will be on campus on 3/12/2012, which is the earlest possible date. The engineer will start working on our XRD on 3/12/2012 or 3/13/2012.
Alighment was done according to instructions of Bruker engineer, but the problem was not solved. A quote was received from Bruker today. A PO request was submitted by Calit2 business office, following a quick approval by Prof. Yee. UCI purchase office is processing the PO.
Received feedback from Bruker engineer. He indicated that this was because of misalignment. I am surprised at the conclusion because no user should change any alignment. I am going to test it again.
