cameras measure the beam size, from which we retrieve the energy spread and the emittance of the beam in both
horizontal and vertical directions. We have designed a robust and simple UV-visible beamline, to measure the electron
bunch profile and length with a streak camera, and to measure the beam quality using a state-of-the-art single photon
counting technique.

The measurement of the ILC emittance in the
ILC beam delivery system and the linac is
simulated. Estimates of statistical and machine-related
errors are discussed and implications
for related diagnostics R&D are in-

Electro-optic devices open the possibility of
ultra-fast scanning systems for use in intratrain
scanning at the ILC, where scanning
rates in excess of 100 kHz may be required.
A first study of the possibilities is presented together with the first results from a prototype system.

The CTF3 Delay Loop Beam Position Monitors Frequency Response
A new laser-wire system has been installed at
the PETRA ring at DESY, Hamburg. The system
is set up to scan in two dimensions using
piezo-driven mirrors and employs a newly
acquired injection seeded Q-switched laser.
The system is described and first results are
presented.
We report on the response of the CTF3 Beam

the results obtained during laboratory measurements
with the wire method and using a 9 GHz network analyzer to simulate the electron beam. We also
show that the coupling impedance of the device decreases, while the transfer impedance improves, by evaporating a
titanium layer of increasing thickness on the internal surface of the monitor.
