Shutter Close Speed for Rapid Data Acquisition

[gerard...@stonybrook.edu]

Just some thoughts/questions about throughput when acquiring data at XPD:

XPD has a Tseries scan plan which allows the user to specify a collection time, a delay time, and a number of repeat acquisitions to perform, which

allows a high degree of customization during data collection. At other user facilities, we've often found that the limiting factor which determines the speed 

of data acquisition is the rate at which the fast shutter is physically able to open/close during the delay interval before a subsequent scan takes place. 

In previous instances, this has led to some misleading readouts on the detector and saved tiff files when the shutter is not given a long enough window

to fully open/close between data acquisitions. 

Is there a good rule of thumb at XPD for the minimum interval to wait between sequential data collections so that the shutter can close properly? I've scanned

the cheat sheet, but I don't believe I've ever seen a minimum hold time recommended for performing Tseries scans at present.
