We will develop gas electron multipliers GEMs) that are robust in negative ion gas to improve the sensitivity of X-ray Polarimeters.
We will develop a technique for fabricating GEMs that will both maintain the required spacing over arbitrarily large areas and be self-aligning. It will be based on separating two tensioned foils.
We will establish the foil tensioning technique and the optimum spacing between the foils.
Improves the sensitivity of exsiting polarimeters by ~ factor of 3.More »
