“The ULTRA Detector System enables capture of one dimensional spectra at extremely high rates. Where CCDs were used to capture a line of data at a time, the ULTRA Detector System offers many orders of magnitude faster time framing. ULTRA is a compact turnkey system. The data acquisition system is attached in a compact form factor unit with gigabit Ethernet out and multiple I/O options onboard.”

The default network setup is (excluding the site network connection):

1GBit Copper network for control communinication between the PC and the Ultra box.

Installation & Module configuration

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


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 the correct information regarding how the camera is exported within the LIMA framework.

Camera initialisation

The camera will be initialized within the :cpp::class::Ultra::Camera object. A TCP and UDP socket connections on the 1GBit port are established

The Ultra requires the following parameters with the recommended settings:

headname          =
hostname          =
tcpPort           = 7
udpPort           = 5005
npixels           = 512

Std capabilites

This plugin has been implemented with respect of the mandatory capabilites but with some limitations which are due to the camera. We only provide here extra information for a better understanding of the capabilities for Ultra cameras.

  • HwDetInfo

    getCurrImageType/getDefImageType(): is set to Bpp16

  • HwSync

    get/setTrigMode(): the only supported modes are IntTrig, ExtTrigMult and IntTrigMult

Optional capabilities
