MUSIC as a E detector
Si detector:
Merit：good energy resolution
Provided by Deqing Fang
Defect：low counting rate(~103)，limited lifetime，limited detective
area。
Ionization chamber: MUSIC(Multiple-sampling ionization chamber)/TEGIC(tilted
electrode gas ionization chamber)
Characteristic：good energy resolution(similar with Si)，high counting
rate(~106)，large detective area (eg. 20cm)。
Counting rate dependence of Z-resolution
Ion Chamber used in 23Al exp@RIPS
TOF (ns) vs. E (MeV) by Ion Chamber
@Day-Two exp. of BigRIPS
Ion chamber (IC) has been widely used as E detectors on RI beam lines
worldwide, e.g. RIKEN, GSI etc. Development of IC on RIBLL will improve the
experimental power of the facility.

RIBLL VME DAQ SYSTEM
完全基于标准C++和ROOT，可移植
性好，易于维护。可视化操作，可在
Windows和Linux操作系统下运行。
网络编程技术：实现获取程序的远程
控制，局域网内有授权的计算机可以
同时获取并存储实验数据
多线程编程：将数据获取、数据存储、
在线分析、获取控制等分开，提高了
获取程序的运行效率
离线处理：程序可以直接将原始数据
转换为ROOT数据格式，使用者无需
再写数据转换程序，使用简单
扩展性好：程序结构模块化，增加插
件无需修改程序
多机框控制：最多9个VME机框，增
加机框无需修改程序

新型PPAC研制状态
return
1、探测器整体设计完成，PCB电路板加
工完成
2、PPAC位置板的镀膜工艺测试中，要求
保证厚度、保证导通
3、PPAC位置读出板设计完成，对LC延
迟电路的测试进行中。使用两种延迟电路
模块，跟旧的PPAC做比较
4、入射窗和出射窗制作多个，PPAC耐压
极限测试中
遇到问题：
1、使用放射源怎样刻度效率？ PMT刻
度时怎样剔除宇宙线干扰
2、薄膜之间间距3mm，压框占2mm，
怎样保证换气充分，且薄膜没有形变。
3、镀膜时有几条不导通时，修补困难
