Luminosity is mostly either design or zero in this simulation. We should collect data on MTBFs and MTTRs of components in existing machines to guide our budgeting process and make up a reasonable set of MTBFs that give a reasonable overall availability. We allowed 25% downtime total. 10% was kept as contingency and MTBFs were tuned so the simulation gave 15% downtime.\n<\/td>\n<\/tr>\n | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Cornell University, in collaboration with Jefferson \nLaboratory, has proposed the construction of a prototype ERL. This \n100MeV, 100mA CW superconducting electron accelerator will be used to \nstudy and resolve the many accelerator physics and technology issues \nof this type of machine. Furthermore, a study that incorporates \nCornell’s CESR e+\/e- ring into a 5 GeV ERL X-ray facility is under \ndevelopment. Such a facility is planed to be formally proposed after \nsuccess of the prototype ERL. \n\n<\/td>\n<\/tr>\n | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

These limitations are connected with \na small response of ODR yield on the beam size in comparison with SR background and with a large \nnear field zone effect for very high Lorenz-factor, such as it is at SLAC FFTB. We consider here \na possibility of application of the artificial phase shift on a slit target, which is very sensitive \nto the transverse electron position and may allow increasing significantly the method sensitivity. \nFor near field zone problem on resolution the model for calculation of ODR from a real size slit \ntarget in near field zone was developed. Usage of this model actually shows a large distortion \nof ODR angular distribution in near field zone for high value of Lorenz-factor. To another side, \nthis model shows the possibility of near field zone effect removing using an optical system in \nthe ODR path. This allows us to realize the measurements of a small transverse size of supper \nrelativistic electron beams. Some tests of this technique at ATF are possible. \nOHP<\/a><\/td>\n<\/tr>\n 2003\/11\/6\n<\/td>\n | Thu.\n<\/td>\n | 13:30-\n<\/td>\n | 2\u53f7\u99282\u968e\u4f1a\u8b70\u5ba4\n<\/td>\n | G.Rumolo (GSI)\u6c0f\n<\/td>\n | ELECTRON CLOUD IN THE GSI-SIS18 | \n AND ROLE OF ELASTICALLY REFLECTED ELECTRONS \n\n<\/td>\n \u5927\u898b\n<\/td>\n | According to the GSI future project, the existing synchrotron SIS18 will | \nbe upgraded to be used as an injector for the planned larger synchrotron \nSIS100. All possible operation scenarios require the acceleration in the \nSIS18 of 4×10^(10) U^(73+) (either packed in 4 80ns long bunches with a \n100ns spacing, or in one single uniform long -500 ns- bunch) up to 1 \nGeV\/u. \nAn electron cloud can therefore form in the machine, as the intensities \nwill be pushed to these unprecedented high values. \nWe study numerically the SEY threshold for the onset of the electron cloud \nbuild up and the possible resulting bunch instabilities. \nWe stress the importance of low energy reflected electrons in the process, \nreferring to recent measurements which have led to a new SEY \nparametrization in which the probability of reflection becomes 1 for \nvanishing energy of the incident electron. \nThe importance of rediffused electrons in simulations is also finally \nshortly addressed as subject presently under study. \n\n<\/td>\n<\/tr>\n 2003\/11\/4\n<\/td>\n | Tue.\n<\/td>\n | 10:00-\n<\/td>\n |
