Recent Microball Parameters

Parameters for experiments GS-87, GS-88, GS-89, GS-90, GS-91, GS-92, GS-93, GS-94, GS-95 or MB-21, MB-22, MB-23, MB-24, MB-25, MB-26, MB-27, MB-28, and MB-29.

Parameters for experiments GS-108, GS-109, GS-110, GS-111 and GS-112, or MB-30, MB-32, MB-32, MB-33, MB-34, and MB-35.

Parameters for experiments GSFMA-6A, GSFMA-6B, GSFMA-7, GSFMA-8,  GSFMA-9, or MB-36, MB-37, MB-38, MB-39, and MB-40.

Parameters for experiments GSFMA-19 to GSFMA-22 or MB-41 to MB-44.

The Microball energy calibration for the experiments MB-36 through MB-40 are listed here: Microball calibration from MB-38.

The parameters for experiments MB-41 through MB-44 (or GSFMA-19 through GSFMA-22) are the same as those for MB-36 through MB-40 listed above.

The alpha-particle energy calibration for the remaining experiments can be obtained from the file: Microball alpha calibrations for experiments M-41 through M-44 and beyond. From now on only the proton energy calibration from 12 MeV protons on ¹²C will be needed.  These were done in MB-42 and analyzed. The slopes and intercepts are given in the file here:  MB-42-proton-cal-coeff.dat. Get the proton energy in MeV (from channel no. 2048 channels, no compression) and then plug it in the formula above for the alpha energy.

Parameters for experiments GSFMA-39 to GSFMA-41 or MB-45 to MB-47. The calibrations for this group of experiments has been done. Here is the proton coefficients file.

Parameters for experiments MB-49 to MB-52.

The configuration file for the experments started on October 28, 2001 are listed here as MBALL_A_10_14_01.txt

You will find here a set of Range-energy files for the Microball absorbers as well as for a few target metals. The proton and alpha ranges are listed in sequence in each file. These were calculated from the Ziegler code TRIM 95 and converted to MeV vs. mg/cm² by D.G.S.
