PfeifferMolecular pumpApplied to compact accelerator mass spectrometry systems
Accelerator mass spectrometry analysis refers to a nuclear analysis technique that combines accelerator and mass spectrometry analysis to determine isotope ratios Accelerators require a clean and oil-free high vacuum environment, typically equipped with a dry pumpTurbomolecular pumpRealize high vacuum environment

Accelerator mass spectrometry system requiresMolecular pumpReason for vacuum extraction:1. The need for electronic acceleration motion; 2. The need for the electronic gun to function properly; 3. The need for microwave electric field in the accelerating tube (to avoid microwave ignition in the accelerating tube, high vacuum must be drawn)

Application of Shanghai Bodong Molecular Pump in Accelerator Case One:Yamagata UniversityMolecular pumpApplied to Compact Accelerator Mass Spectrometry System (CAMS)
The compact accelerator mass spectrometry system CAMS is manufactured by NEC Corporation in the United States. The 1.5 SDH-1 Pelletron accelerator is a dual accelerator (series) electrostatic accelerator This accelerator is designed for use in accelerator mass spectrometry (AMS) systems to measure the amount of 14C in contemporary trace graphite samples with a precision of 0.3% or better The accuracy of its technical indicator age identification is 0.3% between 30000 and 40000 years old This accelerator uses radioactive carbon isotope carbon for dating, with a wide range of applications such as cultural asset dating, environmental science, archaeology, geography, and moreBodong Company for the United StatesNECThe exclusive agency for the company accelerator

This system uses a total of 7 sets of Pfeiffer turbo molecular pumps HiPace 700

Shanghai BodongMolecular pumpApplied to Accelerator Case 2The main building of a large-scale scientific and technological engineering project at the Chinese Academy of Sciences consists of three accelerators: a 150 MeV (150 million electron volts) electron linear accelerator, a full energy enhancer that can increase the energy of an electron beam from 150 MeV to 3.5 GeV (3.5 billion electron volts) in 0.5 seconds, and a high-performance 3.5 GeV electron storage ring with a circumference of 432 meters. After technical recommendation, we have successfully purchased the Boden Pfeiffer turbomolecular pump and dry pump, with specific configurations as follows:
Molecular pump: Hipace 80、Hipace 300、Hipace 700
Molecular pump group: Hicube 80、Hicube 300
Dry pump: ACP 15、ACP 28、 ACP 40

PfeifferTurbomolecular pumpThe pumping speed range is 10 to 2700 L/S, with a maximum speed of 90000 rpm and a maximum ultimate vacuum of 1E-11 mbar.
