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

Öz

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.
