Cryogenic moderator PSI slow muon beam line ISIS EC slow muon beam line oCryogenic moderator method Applied cryogenic moderator method to Efficiency close to 10-4 a pulsed muon source. Initial beam energy spread is ● Yielded about 1 u/sec (*2) about 10eV ●Pulsed source ● Yielded about 700 u/sec (1) ● DC source Time-of-flight showed time resolution was about 90nsec(FWHM),according to A timing counter needs to be ISIS beam pulse width. inserted in the transport line for uSR study Better energy resolution than PSI thanks to absence of a trigger counter. Successful operation since 1993 ●Currently defunct.
