*sigh* I wish I could draw a picture, but I cant do that right now, so I'll just explain it in words:
Its called the Thermal Grid System.
Its original idea was an emitter that fires a reflectable light that you could bounce around your base using the science of optics. If you remember physics lessons at school, they probably told you about light and showed what cool stuff it can do with mirrors, lasers, prisms and so on.
So you could make a whole crazy maze of mirrors and stuff with which you could instantly blast a laser through, killing effectively any invaders inside the base.
There were other uses for this too, like deadly barriers.
I had mirrors and other cool things, but the deflecting part got f'd by CC's physics.
Might be also that I didnt fiddle with those enough since I was pretty short on time for long session testings.
So I just decided to make it fire straight in 4 directions. It limits it slightly, but its still very functional and effective when placed right.
The emitter is an ACRocket and has 4 laser emitter that fire a nice wide beam in all general directions. You must select it in order to fire it, so it aint automatic.
You can, however, set it to fire upwards with a special setting and it can work as an antiair barrier or something like that.
To prevent the laser from eating your base or simply limiting how far it can go, there are "absorber blocks" that counter the laser and suck it in.
When thinking of placing a TGS in your base, you should first carefully plan where you want it to fire and not forget to put absorber blocks where they are needed.
The emitter works also as a storage crate so you can load stuff inside it.
This system makes the bunker very secure and dangerous.
