Направления работы CMS Подготовка мюонной системы детектора CMS в CERN Каналирование Исследование каналирования высокоэнергетичных заряженных частиц в изогнутых кристаллах с целью создания новых методов отклонения, фокусировки, коллимации и вывода пучков на ускорителях высоких энергий и суперколлайдерах; Ядерные реакции Исследование фоторасщепления ядер

Полученные и планируемые результаты по каналированию: Экспериментальное обнаружение и исследование эффекта объемного отражения протонов высокой энергии в изогнутых кристаллах Разработка методов коллимации пучков Большого Адронного Коллайдера (LHC) с помощью изогнутых кристаллов.

О применении исследований From LHC Project Report 918 (2006): “The basic idea of crystal based collimation for the LHC is to use bent crystals for channelling and extracting the halo protons at 6 σ from the central beam orbit onto a special absorber where they hit with large offsets (impact parameters). Due to large extraction angles and high impact parameters the extracted halo protons can in principle be efficiently removed from the LHC beam. For example, a channelling and extraction efficiency of 90% would leave 10 times less load on the standard collimation system, enhancing its performance by a factor of 10”.

Выполненные и планируемые эксперименты: на p-пучке 450 ГэВ (SPS CERN) на e + и e — пучках 180 ГэВ (SPS CERN) на p-пучке 120 ГэВ (кольцо SPS CERN) на пучке 980 ГэВ (кольцо Tevatron FNAL) на пучке 7 ТэВ (кольцо LHC CERN)
