... The splitting process takes about 10 ms in the present 1.4 GeV context. Although this might not be the shortest possible value (no one has yet tried to make it shorter), we can estimate that by multiplying these 10 ms by the ratio of synchrotron frequencies (1.74 = 447 Hz/256 Hz), we get a safe esti ...

This proved invaluable in debugging multiple codes, and also taught me always to think about what I expect the answer to look like, and to investigate any discrepancies between my expectations and the outcome. Rick was also absolutely fantastic at carefully reading my wr ...

Electromagnet



An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.
