The Renovation of the ISOLDE Instrumentation

The ISOLDE [1] instrumentation [2] is mainly based on mechanical scanners, wire-grids and faraday-cups. Additional items are the “fixed needle beam scanner” (FNBS), the tape-station and a device called the “fast faraday cup”. The control system for these devices is being redesigned and reimplemented in order to be integrated in the standard control system of the CERN accelerators complex. While some devices will still be controlled with "usual" standards (VME), the tape-station and the wire-grids will be controlled using industrial PLC’s. In fact, recently, the automates have become fast enough for these applications. This article will describe the different developments in the control electronics, the improvements of the devices themselves and will finish with a short peek at future projects.
