		Acceleration is defined technically as "the rate of change of velocity of an object with respect to time" and is given by the equation :
		One common unit of acceleration is ''g'', one ''g'' being the acceleration caused by the gravity of Earth at sea level at 45° latitude (Paris), or about 9.81 m/s².
		Accelerating acceleration or jerk is the rate of change of an object's acceleration over time.

	Chemistry - Linear particle accelerator
		It may be used to produce X-rays, by accelerating electrons into a target window, or for the production of high energy particles so that the results of particle collisions may be studied, usually with a bubble chamber or other device.
		As the particle bunch passes through the tube it is unaffected (the tube acts as a Faraday cage), while the frequency of the driving signal and the spacing of the gaps between electrodes is designed so that the maximum voltage differential appears as the particle crosses the gap.
		Such accelerators are severely limited in accelerating power since at high voltage energy will be lost due to corona discharge, with electrical energy dissapated into the surrounding atmosphere.

		Generally, the additives are categorized as either suppressors or accelerators, depending on their role in the electroplating process.
		Accelerators usually are unsaturated compounds containing a polar sulfur, oxygen or nitrogen functional group.
		In a simplified approach, it has been estimated that a commercially available chemistry has accelerator agents with a stoichiometric breakdown rate estimated at 2 mg/amp-hr while its suppressor agents break down at a rate of 10 mg/amp-hr (Fig.

		The building of the Linear Accelerator (Linac) was not a random event but rather the result of a series of developments on campus.
		With this unit research was undertaken in the areas of radiological physics, radiation chemistry and the effects of high energy radiation on plants and animals.
		When the construction of the Linear Accelerator was announced in the fall of 1961, it was portrayed as the next logical step on the University’s research path.

	Radiation Chemistry 1968-76
		While radiation chemistry is a unique field, there are significant similarities between radiation chemistry and photochemistry where absorption of lower-energy (non-ionizing) photons produces (mostly) neutral species.
		In addition, radiation chemistry provides access to species in unusual oxidation states; molecules, radicals and ions that are otherwise difficult to produce in quantities sufficient for study, some of which are of biological importance.
		Earlier tests of the model in the Chemistry Department demonstrated that it was consistent with almost all known facts of water radiolysis, but that about one-third of the molecular hydrogen was formed in some other process.

		To determine the roles of excess thermal energy and vibrational energy transfer in radiation chemistry, it is necessary to develop experimental methods to measure these directly.
		The key issues that have been addressed in the design are synchronization of the laser to the radio frequency (RF) of the accelerator, minimization of sensitivity to external mechanical vibrations, variable stretching of the UV pulse from 0.1 ps to 5-40 ps, variable UV energy (0.1-3 mJ), energy stability, and spatial mode profile.
		It is designed to allow a major advance into ultrafast electron-beam-induced radiation chemistry at minimum cost with great potential for future advances in both technology and scientific study in the subpicosecond time domain.
