The fluorescence of the solution was then recorded on a Cary Eclipse fluorescence spectrophotometer (Varian Medical Systems Inc.) using the following settings: excitation wavelength = 340 nm; emission wavelength = 505 nm; excitation and emission slits = 2.5 and 10 nm, respectively. Protein assemblies were examined by transmission electron. This Platform has been optimized to work best with the Google Chrome Browser. To avoid any performance issues, please download here.

In August 2020, Siemens Healthineers announced plans to acquire Varian for $16.4 billion.[4][5]
History[edit]
Varian was founded in 1948 as Varian Associates by Russell H. Varian, Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the Klystron, the first tube which could generate electromagnetic waves at microwave frequencies, and other electromagnetic equipment.[citation needed]
By 1999, Varian Associates had branched into semiconductor, vacuum tube, and medical device fields. On April 2, 1999 these divisions split to become Varian Semiconductor, Varian, Inc. and Varian Medical Systems.[citation needed]
In August 2020, Siemens Healthineers AG announced that it plans to acquire Varian Medical Systems in an all-stock deal valued at $16.4 billion.[6]
Acquired companies[edit]
Varian Medical Systems has acquired other companies including Pan-Pacific Enterprises,[7] ACCEL Instruments,[8] Bio-Imaging Research, Inc.[9] Sigma Micro Informatique Conseil,[10] Argus Software,[11] Dosetek Oy,[12] Velocity Medical Solutions.[13] and MeVis Medical Solutions AG [14]
In January 2018, the company announced the acquisition of Sirtex Medical for $1.3 billion.[15]
In 2019, the company acquired CyberHeart, a privately-held company with intellectual property (IP) that covers the use of radiation in the heart (cardiac radioablation) and other forms of radiosurgery for cardiovascular disease.[16]
Spin-off companies[edit]
On January 30, 2017, spin-off of Varex Imaging Corporation (manufacturing of X-ray imaging products) from Varian Medical Systems had been successfully completed.[17]
Products[edit]
Linear accelerators[edit]
Varian manufactures a range of megavoltageLINACs with varying levels of features and complexity, for example different numbers of multileaf collimators or the ability to perform radiosurgery.[18]

TrueBeam is a radiotherapy system.[19]
The EDGEradiosurgery suite was launched in 2012.[20] The first cancer centers to use the new system were the Champalimaud Foundation in Lisbon, Portugal and Henry Ford Health System in Detroit, Michigan.[21]
Halcyon[edit]
In 2017, Varian launched Halcyon. The system features unique dual-layer MLC that enables high modulation with low leakage for every field or arc.Halcyon is engineered ergonomically to be intuitive, friendly and comfortable for clinical staff and patient alike. This human centered approach means there are fewer parts and protocol for staff to worry about, more time freed up to advance clinical capabilities, and most importantly, more opportunities to provide the highest level of care for every patient. [22]
Proton Therapy[edit]
Varian manufactures the ProBeam Proton Therapy System, with current and planned installations at several sites globally.[23] These are an all pencil-beam scanning proton therapy system utilizing IMTP (intensity modulated proton therapy), which was developed with PSI of Switzerland.[24] Varian also develops medical software and radiology information system for proton treatment planning system.
Ethos Therapy[edit]
On September 16, 2019, during the 2019 American Society for Radiation Oncology (ASTRO) annual meeting, being held Sept. 15-18 in Chicago, Varian announced Ethos therapy, an artificial intelligence (AI)-driven holistic solution[buzzword] designed to increase the capability, flexibility and efficiency of radiotherapy. This new solution[buzzword] is designed to deliver an entire adaptive treatment in a typical 15-minute timeslot, from patient setup through treatment delivery.
Litigation[edit]
Defamation case law[edit]
In 1999 Varian Medical Systems, Inc. sued a former employee for defamation after they posted numerous messages criticizing the company on the Internet.[25] The lawsuit led to the ruling of Varian v. Delfino by the California Supreme Court on the question of whether a trial could proceed while denial of the defendant's anti-SLAPP motion was under appeal. After the state supreme court ruled that a new trial would be necessary because of that technical concern,[26] the case was settled on undisclosed terms.
University of Pittsburgh[edit]
On April 25, 2012 a US federal judge in Pittsburgh awarded attorney fees, costs, and doubled damages totaling $73.6 million to the University of Pittsburgh after the university won a suit on medical patent infringement grounds against Varian.[27]
