摘要：

First results obtained with prototypes of a new type of beam profile monitor based on semi-transparent CVD-diamond are presented. The devices consists of a few micrometer thin membrane on a Si-substrate. Ti/Al-pixel are generated lithographically on-the membrane while the signal wires are deposited on a dielectric in order to minimise signal pickup. Synchrotron radiation tests at 8 keV showed good signal homogeneity, spatial resolution and linearity for low resistivity diamond membranes. Considerable difficulties were encountered in the test of a detector grade diamond membrane. They are most likely related to enhanced surface conductivity and capacitive effects.
