For a full history see document "StatusCHinvestigations.pdf" in this directory. For a quick description see below:

InternalVolume_L2=20_R1=30.sat 						First long model created
InternalVolume_L2=30_R1=60.sat						Increased quadrant radius to reduce frequency
InternalVolume_L2=30_R1=60_Quartered.sat 				Quartered version of previous
A_EndCellsOnly_InternalVolume.sat					Model of end cells only including two bent cross bars and two straight	
B_EndCellsOnly_InternalVolume_ReducedLengthEndCells.sat 		Same as A but with reduced distance between first bar and end wall
C_EndCellsOnly_InternalVolume_ReducedLengthEndCells_Ears.sat 		Same as B but with square ears added on to the sides of the bent cross bars
D_EndCellsOnly_InternalVolume_ReducedLengthEndCells_AntiEars.sat	Same as B but with square ears subtracted from the sides of the bent cross bars	
E_EndCellsOnly_InternalVolume_ReducedLengthEndCells_RoundEars.sat	Same as B but with round ears added on to the sides of the bent cross bars
F_EndCellsOnly_InternalVolume_CirclesToEndFlange_RoundEars.sat		Same as E but the quadrants are taken right out to meet the end walls 
G_EndCellsOnly_InternalVolume_300mmRadEndCells.sat 			Same as E but the end areas are changed from Square(ish) to large circles	
H1_EndCellsOnly_CH_Model_InternalVolume.sat				.... see "StatusCHinvestigations.pdf"			
H2_EndCellsOnly_CH_Model_InternalVolume.sat			 	.... see "StatusCHinvestigations.pdf"
H3_EndCellsOnly_CH_Model_InternalVolume.sat				.... see "StatusCHinvestigations.pdf"


CH_With_Ends_Type_E_InternalVolume_QuadRad=53mm.sat			The long model with the best of the end cell models (type E) 
CH_With_Ends_Type_E_InternalVolume_QuadRad=54mm.sat			.... and now just playing with the quadrant radius to change the frequency
CH_With_Ends_Type_E_InternalVolume_QuadRad=55mm.sat	
CH_With_Ends_Type_E_InternalVolume_QuadRad=56mm.sat 	
CH_With_Ends_Type_E_InternalVolume_QuadRad=60mm.sat 	





**********************************************************************************
CH_With_Ends_Type_E_InternalVolume_QuadRad=49.29mm_DirftTubeOffset=9.633mm

Date created: 17th June 2011
	
Description: CH_With_Ends_Type_E_InternalVolume_QuadRad=53mm model that has been scaled transversally by 93%:

53 * 0.93 = 49.29mm (large radius R1)

....and scaled longitudinally by 50.7%:

19 * 0.507 = 9.633mm (drift tube offset)

Then the number of drift tubes was increased until the total length becomes approximately 1000mm.

**********************************************************************************
CH_With_Ends_Type_E_InternalVolume_QuadRad=46.82mm_DirftTubeOffset=9.633mm

Date created: 20th June 2011
	
Description: The model from the 17th June that has been scaled transversally by 95%:

53 * 0.93 * 0.95 = 46.82mm (large radius R1)

Additionally small radiussed extension tubes were added to the drift tube bores.
