Measurement, development and optical design for Beam Ionization Profile Monitor in Super Proton Synchrotron were a part of the 12 moths working period spent in Beam Diagnostics and Instrumentation group (AB/BDI/BL) in CERN. IPM principally detects electrons produced by ionization of nitrogen gas and delivers a beam profile thanks to electron-photon conversion and CCD imaging. The aim was to determine whether the IPM was able to measure with expected accuracy and repeatability in continuous mode the proton beam vertical emittance under different energy and intensity conditions planned for future Large Hadron Collider. Several improvements were made during the 2003 run and an offline data analysis (via Matlab files) was implemented. Thanks to the measurements, various problems were discovered and should be eliminated in the next generation IPM. Measurements showed a good reproducibility and confirmed the satisfying dynamic range of the instrument. Optical design was made in Zemax program for the new IPM with two optical paths. Two standard doublets and a custom designed 3-element objective were used. Mounted system is being tested.
