The design allowed everyone to see the signs and was cheap costing a dollar per sign. FSU Safety office was impressed with the design they borrowed the idea for signs in new buildings.

Finally the counter to read the sample-detector was added. There was a problem in the read-out but we began to address the issue.

They watched a 10 minute slide show, learned about setting-up protein crystals, harvesting crystals from a hanging drop, flash cooling of the crystal and observered diffraction of protein crystal. ]]> http://www.sb.fsu.edu/~xray http://www.sb.fsu.edu/~xray Wed 16 Jan 2008 11:00:00 EDT Oxford Cryosystems Cryo Diaphragm pump bearing broke during data collection. Replacement bearing for NSK-629Z was found locally. The bearing and new diaphragm were replaced. The pump is now functioning properly. ]]> http://www.sb.fsu.edu/~xray http://www.sb.fsu.edu/~xray Wed 10 Jan 2008 11:00:00 EDT Rigaku PDA-18 meter used for measuring the pin-diode reading was recording out of scale at all scale and switch settings. The meter could not be zeroed properly. We had to replace TL-072CP OpAmp by NTE-858M. The meter is now functioning properly. ]]> http://www.sb.fsu.edu/~xray http://www.sb.fsu.edu/~xray Mon 07 Jan 2008 08:00:00 EDT Soma is back from vacation. XRF regular hours resume.
