Outline of Annual Research Achievements

10**14 eV 以上10**20 eVに及ぶ超高エネルギー宇宙線の起源，組成の解明には宇宙線の核相互作用をシミュレートするモンテ・カルロ(MC)・コードの実験的検証が不可欠である．LHCf実験は唯一このエネルギーに匹敵するCERN LHC加速器を用いてこれを行う．
2013年度は, 陽子・陽子衝突の重心系のエネルギーが√s = 2.76 TeV (TeV = 10**12 eV, 宇宙線陽子エネルギー換算でEcr~4x10**15 eV)及び√s=5.02 TeVの陽子・鉛衝突(Ecr~3.4x10**16 eV) での観測に成功した．中性中間子のスペクトルを導出し，Phys. Rev.Cに発表した．これまでの√s=7 TeV (Ecr ~ 2.6 x 10**16 eV)と同様の結果を得た: どのモデルも完全ではないが，実験から大きくずれるモデルもない．そのうちQGSJET-IIとEPOSが比較的データの再現性がよい．陽子・鉛衝突では，想定外の興味ある現象(UPC = Ultra-Periphera Collision)が観測されていた．鉛原子核周辺の仮想光子と陽子が反応し粒子発生が起こる現象で，宇宙線には関係しないが，MCコードの検証にはUPCの効果を差し引く必要があり，それを可能にした．
2014年のLHCでの最高エネルギー衝突に備え，測定器のプラスチック・シンンチレータを高放射線耐性のGSOに交換し，2013年後半にCERN SPS加速器でテストする予定であったが，SPSが停止したため，予算を繰越し2014年秋に実現した．エネルギーと位置分解能についてMCシミュレーションと一致する結果を得，物理学会で発表した．SPS実験に続き本計画の骨子であるLHCの最高エネルギーでの実験を行う予定であったが，LHCの再稼働が遅れたため2015年度に繰り越した．

Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

CERN SPS加速器により対放射線強度を高めた測定器の較正を2013年秋に行う予定であったが，SPSの１年近い停止が発表され，約１年の延期を余儀なくされたが，2014年秋にはSPSでの較正実験を極めて順調に行うことができた．その後，本計画の骨子であるLHCでの最高エネルギーの実験を行う予定であったが，LHC加速器の再稼働の遅れにより，約半年の遅延を余儀なくされ，2015年度に予算を繰り越した．このやもうえない遅延を除けば，実験を行う側としての状況は極めて順調である．

Strategy for Future Research Activity

本計画の骨子のCERN LHCでの最高エネルギーの実験は2015年に繰り越すことになった．現在６月初めに約2週間の実験を行う予定である(遅延が発表された当初より約2週間遅れ）．また，LHCでの実験の後，念のために行うSPS加速器での装置較正実験を7月末から約2週間行う．準備は万端整っている．
