New membrane driver for DACs available

A new membrane driver for DAC's on SNAP has been developed and built.  Early commissioning has shown that it performs to specification and high quality data can be measured. The relatively low mass of this driver is expected to allow rapid cooling of the DAC to temperatures below 30 K. Cooling tests will be conducted in the next 1-2 weeks.

IDT members Reini Boehler, Stas Sinogeikin and Malcolm Guthrie, in collaboration with Facility staff Jamie Molaison and Neelam Pradhan contributed to the membrane design
