First experimental results from the final focus test beam (FFTB) are reported. The vertical dimension of a 47-GeV electron SLAC linac has been reduced at focal point FFTB by demagnification 320 to height approximately 70 nm.
.
Future linear colliders have hard requirements for the beam transverse position stability in accelerator. A monitor (BPM) with resolution better than 0.1 micron single bunch regime is needed to control of along linac. Proposed BPM based on measurement asymmetrical mode excited by a cavity. Four stages signal processing (space-, time-, frequency- and phase-filtering providing required signal-to-noise ratio) are used obtain extremely high resolution. The set-up was designed BINP installed at...
The effect of low-dose gamma-irradiation (0.1 or 0.2 Gy with a dose rate 0.125 Gy/min) mice on the spontaneous and high-dose radiation-induced level cytogenetic damage during ageing animals was studied using micronucleus test. It shown that single low gamma-radiation induces adaptive response in mouse bone marrow cells, which persists for up to 12 months after irradiation; ability inducing does not depend age at moment adapting γ-irradiation decreases below end lifetime (20 months) animals....
The beam experiments of Final Focus Test Beam (FFTB) started in September 1993 at SLAC, and have produced a 1.7 /spl mu/m/spl times/75 nm spot 46 GeV electron beam. A number new techniques involving two nanometer spot-size monitors been developed. Several diagnostic/tuning schemes are applied to achieve maintain the small spot. This experiment opens way toward world for future linear colliders.
The effect of a pencil scanning beam protons at doses 60 and 80 Gy on the solid form Ehrlich ascites carcinoma (EAC) in mice was studied. It shown that with induced EAC are convenient model for studying hypofractionation schemes under proton therapy.
