Paper Abstract

The addition of a preamplification region is shown to dramatically improve the performance of a standard multiwire proportional counter (MWPC). This improvement is a direct consequence of effecting a large degree of preamplification in a perfectly uniform electric field and then transferring a well defined portion of this charge to a MWPC running at a modest gain. In this way, very large overall gas gains can be achieved without compromising energy resolution. The resulting device is known as a multistep detector.
