Si-MSD: Preliminary prototype setup tested with position readout. Analog test channel and HF-shielding cage needed. Next test at HMI in weeks 34-36 planned.

MSGC: HF-shielded prototype successfully tested with analog and 1D-position readout. Clean high-amplitude signals obtained. 2D-readout and calibration software to be completed. Next test at HMI in weeks 34-36.

CASCADE: Operational, approaching goal of 1 mm spatial resolution

MILAND - Advanced detectors for Single crystal diffraction and Reflectometry
B. Guerard


(PDF, 1.394 MB)
Operational detector of 32 cm x 32 cm, with characterized performances
The MILAND MWPC fulfill most of the technical specifications, although some of them remain to be further studied.
It will be installed on the D16 ILL instrument for further evaluation with “friendly users”
At this stage, we can be already confident that it is the most performing 2D detector ever build for neutron instrumentation
There is still room for improvement (counting rate, uniformity, …)
Several ideas came out from this project, which will be studied in the future: GSPC-MSGC, multiblades, signal processing, …

Since January 2004, CEA-MDN, FRM-II, FZJ, HMI, ILL and ISIS, have actively developed advanced modular devices with the aim of improving and widening the exploitation of spin filters. This work focusses on the following tasks:
- the production of polarised 3He gas using both the spin-exchange (SEOP) and metastability-exchange (MEOP) optical pumping techniques and
- the exploitation of the polarised gas on instruments with improved containers and diverse magnetostatic cavities necessary for the slow decay of the 3He polarisation.
