LHeC Projesi: e-Halka’nın Yeniden Gözden Geçirilmesi

Büyük Hadron elektron Çarpıştırıcısı (LHeC)’in QCD-Explorer aşaması için bir seçenek olarak, Büyük Hadron Çarpıştırıcısı (LHC)’ye teğet olacak şekilde 9 km uzunluğunda yeni bir e-halkası inşası önerilmiştir. 90 MW sinkrotron ışınımı kaybı ile L=1033 cm-2 s -1 ışınlığa ulaşılabileceği gösterilmiştir. ERL60LHC’nin temel versiyonu ile örtüşen bu ışınlık değeri, LHC için (Parton Dağılım Fonksiyonu) PDF’lerin kesin olarak tayini, QCD temellerinin keşfi, ve özellikle Q2 ≈ 1 GeV2 ’de 10-6 ’ya kadar küçük x Björken bölgesinin belirlenmesinde yeterli olacaktır. Ayrıca, ERL60LHC’nin temel ve geliştirilmiş versiyonları üzerine bazı öneriler de sunulmuştur. Geliştirilmiş ERL60LHC’nin L=1034 cm-2 s -1 ışınlıklı versiyonu, 160 MW’ın üzerinde yüksek bir şehir şebeke elektrik gücü gerektirdiği gösterilmiştir.

The LHeC Project: e-Ring Revisited

Construction of a new 9 km long e-ring tangential to the Large Hadron Collider (LHC) has been proposed as an option for QCD-Explorer stage of the Large Hadron electron Collider (LHeC). It is shown that L=1033 cm-2 s -1 can be achieved with 90 MW synchrotron radiation losses. This luminosity value, which coincides with basic version of ERL60LHC, will be sufficient for precise determination of (Parton Distribution Function) PDFs for LHC, as well as exploration of QCD basics, especially small x Björken region up to 10-6 at Q2 ≈ 1 GeV2 . In addition, some comments on basic and upgraded versions of ERL60LHC are presented as well. It is shown that upgraded ERL60LHC version with L=1034 cm-2 s -1 requires high wall plug power exceeding 160 MW.
