Digital Equipment Corporation RMO3P is a disk pack data cartridge removed from 1980's VAX-11. It measures 15" wide and 4" high.
The cartridges had a total capacity of up to 8.5 TB. They were actually manufactured by the Fujifilm company, used Barium Ferrite (BaFe) magnetic particle technology to store the user data and were equipped with a Radio-Frequency IDentification (RFID) chip (for quick access to the cartridge metadata).\ The tape length inside of each cartridge is 1147 meters while it is only 5.2 microns thick. Once mounted in a tape drive, the media moves over the drive head at the speeds of up to 4.7 meters/second when reading or writing, but up to 13 meters/second when locating to a file. Since 2019, all data that had been stored on such cartridges have been copied onto more modern supports. As of 2022, CERN uses similar tapes produced by other suppliers and having a capacity of up to 20 TB.
Slice of the Large Hadron Collider (LHC) prototype beam tubes in dipole magnet The LHC is the world’s largest and most powerful particle accelerator that accelerates and collides two beams of protons or ions to near the speed of light in opposite directions. It first started up in 2008, and is the latest addition to CERN’s accelerator complex (2025). The LHC consists of a 27-km ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. The high bending and accelerating fields needed can only be reached using superconductor magnets at very low temperature (‑271.3°C). There are 1232 dipole magnets like this prototype in the LHC, used to guide the particles around the 27 km ring. Dipole magnets must have an extremely uniform field, which means the current flowing in the coils that produce the magnetic field has to be very precisely controlled. Nowhere before has such precision been achieved at such high currents. The temperature is measured to five thousandths of a degree, the current to one part in a million. The current creating the magnetic field pass through superconducting wires at up to 12 500 amps, about 30 000 times the current flowing in a 100 W light bulb. Since the LHC accelerate two particle beams moving in opposite directions, it is really two accelerators in one. To keep the machine as compact and economical as possible, two dipole magnets are built into a single housing.

A drift tube from the Linac 1. This was the first tank of the linear accelerator Linac1, the injection system for the Proton Synchrotron, It ran for 34 years (1958 - 1992). Protons entered at the far end and were accelerated between the copper drift tubes by an oscillating electromagnetic field. The field flipped 200 million times a second (200 MHz) so the protons spent 5 nanoseconds crossing a drift tube and a gap. Moving down the tank, the tubes and gaps had to get longer as the protons gained speed. The tank accelerated protons from 500 KeV to 10 MeV. Linac1 was also used to accelerate deutrons and alpha particles for the Intersecting Storage Rings and oxygen and sulpher ions for the Super Proton Synchrotron heavy ion programme.

Model of the LEP tunnel as it is in the 1990's. LEP(Large Electron Positron collider) was the world biggest accelerator.
This is a slice of a Large Electron Positron collider (LEP, for short) dipole bending magnet, made as a concrete and iron sandwich The bending field needed in LEP is small (about 1000 Gauss), equivalent to two of the magnets people stick on fridge doors. Because it is very difficult to keep a low field steady, a high field was used in iron plates embedded in concrete. A CERN breakthrough in magnet design, LEP dipoles can be tuned easily and are cheaper than conventional magnets. With its 27-kilometre circumference, LEP was the largest electron-positron accelerator ever built and ran from 1989 to 2000 at CERN.
