A video distribution and analog monitoring system for the Jefferson Lab FEL

PDF Version Also Available for Download.

Description

The Jefferson Lab Infrared Free Electron Laser (IRFEL) has used the 200MHq 16 x 16 buffered crosspoint switch, AD81 16 to implement video and analog distribution. These switches are configured as 64 inputs x 16 outputs packaged into a rack mount chassis, which is used for both the video and analog systems. These systems are controlled through EPICS. This paper describes how the 256 point matrix is implemented to support the electron beam diagnostics for the FEL as well as support for the user lab video demands. A switcher chassis is also connected to three digital oscilloscopes to provide an ... continued below

Description

The Jefferson Lab Infrared Free Electron Laser (IRFEL) has used the 200MHq 16 x 16 buffered crosspoint switch, AD81 16 to implement video and analog distribution. These switches are configured as 64 inputs x 16 outputs packaged into a rack mount chassis, which is used for both the video and analog systems. These systems are controlled through EPICS. This paper describes how the 256 point matrix is implemented to support the electron beam diagnostics for the FEL as well as support for the user lab video demands. A switcher chassis is also connected to three digital oscilloscopes to provide an Analog Monitoring System (AMS). The scopes are in turn connected to the video switcher using a VGA to video adapter. The analog signals can then be viewed on any color monitor connected to the video system. The video switcher feeds a 16 channel 1:4 video distribution amplifier and to a ''video-to-fiber'' transmitter. All of the 128 video and 128 analog channels are available locally in the FEL building and remotely at the CEBAF main control center.
