Abstract :
The position monitor using the stretched wire method is being developed as a component of the active alignment system for particle accelerator equipment, such as RF cavities and magnets. The RF voltage is supplied to the stretched wire and the monitor measures the change of capacitance between wire and pickup strip. Present resolution, limited by the electronics noise, is about 5 nm
