  he Com­pact Lin­ear Col­lid­er (CLIC) study in­ves­ti­gates the fea­si­bil­i­ty of a high-en­er­gy elec­tron-positron lin­ear col­lid­er op­ti­mized for a cen­tre of mass en­er­gy of 3 TeV. To achieve the high ac­cel­er­at­ing gra­di­ents, the RF power is pro­duced by a novel two-beam ac­cel­er­a­tion method in which a de­cel­er­at­ing drive beam sup­plies en­er­gy to the main ac­cel­er­at­ing beam. The linacs are ar­ranged in mod­u­lar struc­tures re­ferred to as the two beam mod­ules which cover 42 km of beam­line. Beam loss­es from ei­ther beam can have se­vere con­se­quences due to the high in­ten­si­ty drive beam and the high en­er­gy, small emit­tance main beam. This paper pre­sents re­cent de­vel­op­ments to­wards the de­sign of a Cherenkov fiber BLM sys­tem and dis­cuss­es its abil­i­ty to dis­tin­guish loss­es orig­i­nat­ing from ei­ther beam.
