Detectors

It seems the problems concerning reminiscence effects in the new detectors for ALFOSC and FIES have been resolved, but the planning issues still remain. The NBI reorganised the management of the CCD project in Autumn 2014. The main advance has been our (the NOT and NBI) convergence on a detailed planning, and on-going discussions on the precise details of a contract. It was agreed with the NBI to update the current NOTSA/NBI contract with revised information regarding 1) specific requirements, 2) time plan for the completion and commissioning of the FIES and ALFOSC systems and 3) cost. A specific contract proposal detailing this and the related cost is expected soon. The fact that a specific time-line will be defined in the contract gives us some confidence that the planning will be kept.

On La Palma, two new instrument computer have been purchased for use with the new FIES CCD system. One for operation and the other for development. They are ready to begin the software test for the new FIES system as soon as a new, clean, version of the CCD3 control software have been released by NBI.
