MarCCD

../../../_images/marccd.png

Introduction

The SX165 features a round, 165 mm diameter active area, and a versatile, high resolution CCD chip. It is the ideal X-ray detector for research applications with both synchrotrons and rotating anode X-ray sources.

Prerequisite

The MarCCD software server should be started on the MarCCD host computer, by running the command:

$ marccd -r

Then you can launch your lima/marccd client on another host, as the MarCCD server can be reached by network

Installation & Module configuration

Follow the generic instructions in build_installation. If using CMake directly, add the following flag:

-DLIMACAMERA_MARCCD=true

For the Tango server installation, refers to Tango Device Server.

Initialisation and Capabilities

Implementing a new plugin for new detector is driven by the LIMA framework but the developer has some freedoms to choose which standard and specific features will be made available. This section is supposed to give you good knowledge regarding camera features within the LIMA framework.

Camera initialisation

There are 4 parameters to be filled by your Lima client:

  • The IPAddress of the host where the marccd server is running
  • The port of the marccd server process
  • The detector target path: the path where will be saved the marccd image files
  • Reader timeout: in ms, the timeout after which the plugin will be in fault if no marccd image file is present

Std capabilities

This plugin has been implemented in respect of the mandatory capabilites but with some limitations according to some programmer’s choices. We only provide here extra information for a better understanding of the capabilities for the MarCCD camera.

  • HwDetInfo

    • Max image size is : 4096 * 4096
    • 16 bit unsigned type is supported
  • HwSync

    • trigger type supported are:

      • IntTrig

Optional capabilities

  • HwBin

    • 2 * 2
    • 4 * 4
    • 8 * 8
  • HwRoi

    TODO

Configuration

No Specific hardware configuration is needed.
