Collision Chambers
Collision Chambers are where you smash particle beams into each other to create new and possibly exotic particles.
Collision Chambers are 17 long square prisms of Particle Chamber Casings or Particle Chamber Glass. The ends must be squares of odd size from 3 to 15 across (there no really benefit to go above 11). Down the middle of the long axis must be a line of Particle Chamber blocks. At each end there must be a Particle Chamber Beam Port in input mode. 2 blocks away from each square end, on the horizontals, there must be Particle Chamber Beam Blocks connecting the centre axis to an Particle Chamber Beam Port in output mode. They must also have a Collision Chamber controller and at least one Particle Chamber Energy Port in the casing.
An Example 7x7x17 Collision Chamber is shown:
Detectors can be place in Collision Chambers this increases the efficiency of the chamber which makes reactions more efficient. For them to work they need to be place within a certain distance from the Particle Chamber Blocks (the centre axis) shown on their tool tip. Detectors add to the power usage of the collision chamber. Note power is used only when the chamber is running.
7x7x17 Collision Chamber full of detectors in it:
Particle beams at the right total energy and focus must be piped into each input port to work. Power must also be supplied.
Here is an example:
Here protons at 90 GeV, 100 pu/t and 9.96 focus are being smashed into antiprotons at 130 GeV, 50 pu/t and 5.96 focus. The total energy of the Collison can be calculated using Et=2(E1E2)0.5 so 2(90 GeV*130 GeV)0.5 = 216.333 GeV. This is what is shown in the gui.
The Collison makes glueballs, w + bosons, W - bosons and charmed eta mesons (top 2 outputs then bottom 2 outputs) each at 13.175 GeV, 45 pu/t and 5.28 focus. to calculate these numbers we need to look at the recipe in jei:
Here we see to do this recipe we must have the total energy in the range 179.997 GeV-269.996 GeV. Which 216.333 GeV is. Hovering over the proton we see it says amount 1 pu, energy 89.999 GeV, focus 5. The energy is irrelevant and is just half the minimum range energy rounded 179.997/2=89.9985. The amount is also irrelevant. The focus is the minimum focus need for the proton.
To calculate the energy of the beams outputted we do E=(Et+Q)/n where Et is the input total energy, Q is the energy released and n is the total amount of particles outputted in the recipe. In our example Q = -163.634 GeV and each of the 4 particle types outputted have an amount of 1 so a total of 4 particles. So (216.333 GeV+-163.634 GeV)/4=13.175GeV.
To calculate the amount of pu/t of each particle we make we use aout=amin(a1,a2)Σc where a is the amount said in the recipe in the case of the w + boson it is one (it also one for the other particles). a1 and a2 are the amounts of the input beams. Σc=min(ση(1-|E1-E2|/(E1+E2)),1) where σ is the recipe Cross-Section and η is the chambers efficiency. In our case σ=2% and η=5600% so Σc=min(0.02*56(1-|90 GeV-130 GeV|/(90 GeV-130 GeV)),1)=0.916. Then for the W+ boson 1*min(100,50)*0.916=45.8 which is 45 after rounding down. Note: that the energy factor in Σc means that having both beams with the same energy i.e. E1=E2 gives you the most particles.
The focus of the output beams is the same as the input beam minus the distance it travelled times the beam attenuation rate.
In the gui the output slots are numbered 1 to 4. 1 at the top left, 2 at the top right, 3 at the bottom left and 4 at the bottom right. By default the beam ports on the collision chamber correspond to these like shown:
This is looking from the top. The black arrows represent the beam ports. The physical location of the port is labelled A to D, the slot the port corresponds to is labelled with its number. The blue arrow is in the positive direction (either positive X or Z depending on the orientation of the collision chamber). Switching the outputs is done by shift right clicking an output port. It matters which port you click. Clicking a port will switch the corresponding output slot with the one clock wise of it (red arrow). So in this starting configuration clicking A will change A:2 and B:1. clicking it again will switch it back to A:1,B:2.
A more complex example: lets say starting in the default configuration (A:1,B:2,C:3,D:4) you want to switch to (A:3,B:2,C:1,D:4). To do this click C, so now (A:1,B:2,C:4,D:3). Then D, so now (A:3,B:2,C:4,D:1). The finally C again.
