	At S-LSR in ICR, Kyoto University, approaches to multi-dimensional laser cooling of Mg ions with the use of synchro-betatron coupling has been applied in addition to the realization of one dimensional ordering of 7 MeV proton beam with application of an electron beam cooling. In the present paper, recent results of transverse cooling of bunched beam will be presented together with an aproach to provide a short bunch 7 MeV proton beam with a high peak current to make bio-medical irradiation of biological cells.

	Construction of measurement system is presented. The system is based on special magnetic sensor (compass) with a mirror attached to the compass needle. The needle with the mirror are suspended on gimbal suspension and can rotate in two directions. Measuring reflected laser beam deflection one can measure field line straightness with accuracy up to 10-6 rad. The compass is installed inside vacuum volume of the cooling section on special carriage that moves on rail along the section via special tape. To calibrate the compass special test bench was made. The calibration procedure allows to determine and to diminish compass inaccuracy appeared during manufacture and assembling. Results of calibration of the compass on the test bench are presented.

	For the cooling of proton and Ion beams a well established overlap between cooling beam and circulating beam is needed. The new relativistic electron cooling devices have special demands on the diagnostics which can be used to characterize the cooling beam. Due to high voltage breakdowns they only allow a very small beam loss so non-invasive beam diagnostic methods are necessary. A system based on beam induced uorescence (BIF) was installed at the 100 keV polarized test setup at the Mainzer Mikrotron (MAMI). First results of the measured photon yield as a function of beam current and residual gas pressure will be presented. In addition a Thomson scattering experiment is planned at the same test setup. This method enables the measurement of other observables of the cooling beam like the electron beam energy or the electron temperature. The design of the experiment as well as the challenges will be discussed.
