Technical Data

Up one level
A repository of important technical data and information about UMER.
Technical Data UMER Magnet Data (2010)
Summary tables of UMER magnet parameters, obtained from first-principles calculations. These revised numbers use the most accurate models available as of 10/2010.
Technical Data UMER Beam Parameters - Normal
UMER Beam Parameters for the operating point with 1.826 Quad Current
Technical Data UMER Beam Parameters - Other
UMER Beam Parameters for other popular operating points with Quad Current Iq
Technical Data UMER 76 deg. Matching Settings 2006-10
The table below lists the updated magnet currents for best matching for the most commonly-used beams, for a target sigma_0 of 76 degrees. The calculations use the new hard-edge model, assume new quads throughout the ring, and include bends. See Notes below for some additional information.
Technical Data MAD description of UMER - Ring
Description of the UMER ring lattice using the Methodical Accelerator Design (MAD) language. Reflects the change of all the ring quads to the new type (3rd generation) week of 8/16/2006.
Technical Data MAD description of UMER - Injector
Description of the UMER Injector lattice using the Methodical Accelerator Design (MAD) language. Reflects the repositioning of the SOLENOID in June 2006.
Technical Data Pulsed Magnet PS Calibration
Calibration value for the Y-section's pulsed magnet power supplies
Technical Data BPM Calibration Data
Beam position in the horizontal plane is determined by dividing the difference of the two horizontal (right and left) signals by their sum and applying the offset and resolution factors determined in calibration. Since X and Y are decoupled, repeating the process with the vertical (top and bottom) signals creates an XY pair at which the beam centroid lies. The equations are: X = (Right-Left)/(C(Right+Left))-B/C and Y = (Top-Bottom)/(C(Top+Bottom))-B/C Where Right, Left, Top and Bottom are the voltages measured from the corresponding signal plate, C (slope) is the calibration number and B (X-intercept) is the offset number.
Technical Data Earth Magnetic Field Measurements 2004-2009
Collection and Summary of Earth Magnetic Field Measurements 2004-2009 by Dave Sutter, et al.,
Technical Data E-RING-Apertures
Technical drawings of apertures in the UMER gun (from D. Kehne).
Technical Data UMER Gun Latest AutoCAD Drawings
According to Paul Haldemann these AutoCAD drawings represent the latest drawings of the UMER gun.
Technical Data Archived Technical Data
Technical data specifying current configuration will be found in parent folder. Data which is not up to date will be found here. This archived data is useful, for instance, for simulating past experiments.
Technical Data UMER Design from the old website
Click with Caution. This link contains additional information about the UMER design, but some of it (like the magnet information) may be out of date. The old Website has not been updated since the early 2000s.
