W.R.Nelson 氏の「EGS4の歴史と現状」、波戸氏の「低エネルギー光子輸送の改
良」、A.F.Bielajew 氏の「PRESTA」に関する招待講演を企画しました。EGS4の
現状と今後を知る良い機会になると思います。又、講習会の２日目（８月２５日）
に、A.F.Bielajewが"Step-size artefacts and PRESTA" と題する特別講演を行い
ます。既にEGS4を使いこなしている方にも参考になると思います。できるだけ多
くの方が参加されるよう呼びかけます。まだ、Registration をされていない方は、
できるだけ早急に平山まで Registration Form をお送り下さい。
　ホテルとＫＥＫ間のバスをホテルに運行してもらうためには、一定数以上の宿
泊者が必要なので「ホテルに宿泊可能な方」は事務局で用意したホテル東雲を利用
していただくようお願いします。（予約は、事務局でまとめて行います。）
