Proton: Proton Energy
built 634 days ago
Proton radiotherapy deposits most of its energy at a specific depth and then stops entirely. This allows the physician to tailor the deposition of dose to the specific depth and shape of the tumor while simultaneously reducing the damage to surrounding normal tissue. The advantages of proton radiotherapy over conventional radiotherapy are emphasized in areas of the body with critical adjacent structures (e.g. eye, brain, base of the skull, spine, and prostate) as well as in pediatric tumors.

Proton therapy uses an external beam of precisely-targeted, high-energy protons. The primary difference between proton beam therapy and conventional radiation therapy is the ability to deliver radiation more precisely to the tumor without damaging healthy tissues. There are only five full-scale proton beam centers currently operating in the United States; the closest to Seattle is in southern California.

Northern Power and Proton Energy merged to form Distributed Energy Systems in late 2003. The combined company provides industrial and commercial markets with products and services offering greater control over the supply and cost of power, as well as increased efficiency and reliability.

The facility will allow the Company to consolidate all operations under one roof and provide the manufacturing and development space needed for Proton Energy's growth over the next several years. Proton Energy plans to manufacture its HOGEN(R) hydrogen generators and its UNIGEN(R) regenerative fuel systems at this facility. Proton's employees will move from its two locations in Rocky Hill, CT to the new headquarters when completed.

The proton exchange membrane electrolysis technology developed by Proton produces energy by converting water into hydrogen and oxygen to power the airship. This PEM reaction happens in a controlled environment, enabling Proton's regenerative fuel cell system to provide the airship with its necessary power. This same technology is ... used to provide back-up power in the telecom industry, as well as for serving huge commercial markets for hydrogen, including cooling power plant generators.

Powerful magnets then bend the proton stream in to a circular path and then control then it as the stream is accelerated to near light speed inside a cyclotron. The speed of the resulting beam, and therefore its energy, is measured in electron volts, and the higher the electron voltage, the heavier the impact when the beam hits a tumor in a patient's body.
