3.8 Starting Data Collection
Data collection can be started by pressing the "Go" or "Go/Erase first" button in the
mar345−Change Parameters window. It is a good idea to always let the plate clean first
before actually starting the data collection.
In Multiple Data Sets mode, before actually sending the command to the scanner the
mar345−Run Parameters window will pop up. This window gives an overview ofthe currently
programmed data sets. The buttons in the lower part of the window come with different
layouts:

To start data collection you will have to press the "Go" button in this window. During data
collection the mar345−Run Parameters window monitors the progress of the data collection.
The window can be opened by selecting the "Progress" option in the "Windows" submenu
(see 3.2.1). Active data sets are highlighted. Start
−ϕ
and Image will be updated. The number
of oscillations is given by the multiplier in the
∆ ϕ
field. If the scanner is idle, this window
cannot be obtained.
3.9 Stopping Data Collection
Data collection can be stopped by pressing the "Stop" button in the main window or by
pressing the "Stop" or "Abort" button in the mar345−Run Parameters window. If the
scanner is scanning or erasing the imaging plate, this cycle will always be finished. Pressing
"Abort" in this moment will be the same as pressing "Stop". Otherwise, "Abort" closes the
X−ray beam shutter immediately and stops
ϕ
or distance movement.
