  电子学（Wei Wei）：
  
  散热：由探测器提出需求，交由机械组进行仿真计算
  
  桶部-端盖间隙：机械组提出6cm，对电子学来说满足要求。
  
  端盖计数率显著比桶部高，需要通过模拟确认需求。
  
  端盖量能器设计：
  
  有初步设计图纸。
  
  软件几何的工作：ECAL端盖几何有安排，HCAL暂时人力短缺。
  
  端盖HCAL：2种设计：高颗粒度/R向分层。可以根据Barbar等物理过程进行初步评估和优化（Hengne）。
  
  机械（Shaojing）：
  
  ECAL barrel重量分配在HCAL上，可以把ECAL机械的栅格结构厚度从1cm减小到5mm。
  
  加入2mm打孔结构，用于晶体固定，留固定窗口供电子学光电器件。
  
  按16边形*2，矩形+梯形结构进行的设计。（Comment：更新到正反梯形方案）
  
  Review of TDR meeting （Yong）: in slides.
  
  机械，软件，造价估计根据新尺寸进行调整。
