OutlineOutline

1) Download & install

“MyGLG4sim” – full detector simulation

2) Check out the output

(basically, followed up the status talk files of Dr. E.J.Jeon)

(but, before gadolinium support, yet)

2) Plan

PlanPlan

1. Need to study more on the physics process

2. Need to think what variables we can look at

3. Need to understand more on the code behavior

4. Make sure for Gd support on the code

5. Look at variables before & after detector simulation
