Pionic and muonic X-rays.

The first run with a hydrogen target will concentrate on the measurement of the \( 3\rightarrow 1\) transition at two different pressures. We plan a total beam time of 10 weeks presumably for the year 2000. The experiment has to be set up in the \( \pi E5\) area and requires the full intensity of the proton beam of 1.5 mA with the full thickness of the pion production target E.

The second run period should be devoted to the \( 2\rightarrow 1\) transition. A total beam time of two months is planned for the year 2001 with a preparatory phase of two weeks and two periodes of three weeks for two pressures between \( 15bar\) and \( 40bar \).

A third run of two months is planned for the year 2002 for a measurement at lower pressures. Depending on the date of the scheduling and termination of the X-ray measurement with the ECR source the pion/muon measurements are planned to start in the years 1999/2000 and will last for about three years.
