Windows based camera IOC with a SMB branch

Basic concept

• easy to compile (EPICS-base, GNU-make)• fast switching between IOC and manufacture software• viewer for alignment and recording• high throughput data transfer branch• different ways to use and control the camera (Java/Matlab; pure EPICS)

Windows based camera IOC with a SMB branch

implemented Software Development Kits (SDK)

• PCO Sensicam e.g. Sensicam / UV• PCO HS e.g. 1200-hs, DIMAX• Andor e.g. Newton, Clara, iDUS• Pylon (Basler)

Windows based camera IOC with a SMB branch

Java object• JCA (Cosylab)• One central object for all camera types.• Can be used in MATLAB• The users can use one interface to program by different cameras

Data transfer via SMB

• the IOC writes the data direct to a SMB fileserver• user specified login• password is secured via RSA/1024• Java program for the password

Windows based camera IOC with a smb branch

Problems

• using the camera dynamically (e.g. power-switch, USB or GigE)• master / slave (e.g. long exposure times)• black box SDK (e.g. high data rates)• Monitors in MATLAB (memory leak)

Windows based camera IOC with a smb branch

Used

• OBLA gun test stand• opt. streak-camera of diagnostic of SLS• TOMCAT beamline high speed tomography• hard x-ray streak-camera (own project)

Windows based camera IOC with a SMB branch

Summary

• Windows-based camera support• users can switch between “normal” and IOC – mode• several entry points to use the system• the client side is more flexible (e.g. standalone Java or MATLAB)• SMB access
