SACLA Technology
SACLA brings together a number of world-class technologies. Here are few of them.

Electron gun that produces high beam Accelerate electrons efficiently with a C-band Accelerator
■Owning to the development of a graphite heater,
the cathode can operate stably at a temperature of 1450 C.		   ■A C-band accelerator (5.7 GHz), which can accelerate electrons with twice the gradient of earlier machines, has made it possible to design a very compact accelerator.
■By processing high purity oxygen-free copper to a precision of 1 micron, were able to build an accelerator tube with an acceleration gradient of 350kV per centimeter.

In-vacuum undulators-generates X-ray laser light Beamline experimental stations for advanced experiments
■Since the rows of magnets are set within the vacuum duct, they can be placed within 1.5 mm of the beam, allowing the magnets to have a strong influence on the beam.    ■A high-quality x-ray mirror with a surface precision of 1 nanometer, and a control device, developed jointly with Osaka University, to control the orientation of the mirror.

Accurate & stable control devices behind SACLA SACLA Detectors
■Control technology that functions in a high-voltage, high-noise environment.
■A high-stability power supply that controls electromagnets at a precision of 20 ppm.
■A stepping motor system equipped with a position detection device that functions in a high-radiation environment.		    ■The “eyes” that can accurately visualize anything from a single x-ray photon to masses of photons are composed of a sensor (left) and a high-speed high-precision electronic circuit(right).

High-stability trestle to support the accelerator Accurate & stable control devices behind SACLA
■A device was developed to polish the concrete floor to a precision of 50 microns, and the vibration resistance of the trestle was greatly improved by increasing the contact between it and the ground.    ■An electron beam position monitor that can measure the position of the beam to within 1 micron
