  • A velocity selector is used in accelerator mass spectrometry to select particles based on their speed.

    A velocity selector is used in accelerator mass spectrometry to select particles based on their speed. The velocity selector is composed of orthogonal electric and magnetic fields, such that particles with the correct charge to mass ratio and speed will be unaffected, and other particles will be deflected. If the Electric Field is oriented down, What is the direction of the Magnetic Field? A charged particle moves through the velocity selector at a constant speed in a straight line. The electric field...

    PROBLEM 1 – A velocity selector (Wien Filter) has an electric field of magnitude 2470 N/C, directed vertically upward, and a horizontal magnetic field that is directed to the south. Charged particles, traveling east at a speed of 6.50 × 103 m/s, enter the selector and are able to pass through undeflected. When a different charged particle with an electric charge of +4.00 × 10-12 C enters the selector traveling east, the net force acting on it is 1.90 ×...

    1. A speed selector is a device that uses both electric and magnetic fields to select particles with only a certain value of velocity. (a) If a positively charged particle goes through a region of space where the electric field points directly upwards and the magnetic field points out of the page, draw a free body diagram indicating the electric and magnetic forces this particle feels. (b) If the particle can go through this region without being deflected (that is,...

    Problem 1a: Velocity Selector: Show that with the right ratio of electric to magnetic field strength a particle of velocity v will proceed through both fields in a straight line at constant speed (hint: you will need an equation containing v. Also: what does the straight line at constant speed give you?). Assume that the angle of the velocity vector relative to the magnetic field vector is 90 degrees. (15 points) b: Show mathematically that the charge magnitude and sign...

    The velocity selector in in a mass spectrometer consists of a uniform magnetic field oriented at 90 degrees to a uniform electric field so that a charge particle entering the region perpendicular to both fields will experience an electric force and a magnetic force that are oppositely directed. If the uniform magnetic field has a magnitude of 11.2 mT, then calculate the magnitude of the electric field that will cause a proton entering the velocity selector at 16.1 km/s to...
