In internal synchromode, MCA acquisitions terminate when the amount of time elapsed, either real or live in respect of mcasetup time mode settings, matches the time the MCA internal timer was preset with. The live time is the real time substracted the electronics dead time. Mcasetup AUTO-RUN option (toggling enabled /disabled) does the same as mcaon / mcaoff. On the other hand, mcaacq always run the MCA, but never run the counters, whatever mcaon or mcaoff is set.

mcaoff disables the MCA to be addressed from those commands. If it happens that it is taken out, the macros disable themselves automatically, as well as they enable back in case of a MCA is configured again.Д«oth COUNTERS and MCA are operated simultaneously from ct and scans commands if mcaon is set. MCA macros are able to detect that a MCA has been configured. In SPEC config, select MCA TYPE ESRF MCA, TCP MODE. SPEC addresses it through a device server, called McaAIM that runs on HP-UX machines. It is remote controlled via Ethernet LAN. The GPIB is addressed by the device server, so you do not necessarily need to declare it in SPEC, but only Themis T409 VME Board is supported McaMB server runs on OS9 crates. The GPIB is addressed by the device server, so you do not necessarily need to declare it in SPEC, but only HP E2050 LAN/HPIB controller is supported McaSICL server runs on HP-UX machines only. The GPIB interface can be any of those supported by SPEC. In SPEC config, select MCA TYPE Silena 73XX MCA (GPIB), TCP MODE. Be more particularly aware that the acquisition times are not known by the GUI, so if you save the spectrum from the GUI, they wont be included in the file. The GUI is not capable of sending control commands to the hardware.

They are two seperate sets of ROI definitions. For instance, the ROIs defined from SPEC or from the GUI are not connected together. It is at the moment only capable of monitoring the data acquired, as there is no connection between SPEC and that GUI, appart from the spectrum data itself and its calibration parameters, both stored in shared memory. A Graphical User Interface is also available.ДЄbout the usage of the Graphical User Interface (GUI) : acquire, plot out, save spectrum for each point of a scan. MCA control is inserted in SPEC internal code, making it possible to automatically operate the MCA, from standard SPEC counting and scanning commands, e.g. start, stop, init, read memory, etc., as well as with more sophisticated features such as ROIs, channel calibration, peak search, data saving and recovering, etc. These macros provide users with basic MCA commands, i.e.
