Using simulations, we found the best geometry of the collimator is the one with a rectangle aperture and all of them are placed in two groups with an orthogonal orientation, which will have good resolution and sensitivity, and also be easy to manufacture. The rectangle aperture gives good imaging accuracy along the short side, and wide viewing along the long side. The orthogonal orientation for collimators will allow us to observe the source and the background simultaneously.
