GIP - Mixes Group Cross Sections for DOORS
GIP input deck is instructions for combining elemental cross sections using any combination of elements from a given library file or from manually-entered elemental cross sections
each Pl component listed as separate materials
Pl components are built by instructions
mixtureN = mixtureN + materialM*density
input file: N M density
densities MUST be atom/(b cm) strict formatting, not very readable steep learning curve

Need a better way to make GIP input decks
treat materials as materials, handle Pl components behind-the-scenes
easier way to enter data by hand easier way to specify material compositions eliminate the need to learn formatting ability to edit existing input decks (back-
compatibility) perhaps even run GIP without ever seeing the
input deck

GipGui
written in Java, machine independent creates new and edits existing input decks manually entered data input into easy-to-read
table user can specify material composition 8 different
ways elemental and nuclear data on main screen extra comments and data embedded into GIP
standard input file

Requirements and Restrictions
Requirement a library index file describing
what is in the actual library (GipGui can help user create this)
Restrictions "=gip" or "=end" not permitted Stacked cases not allowed Only comment character is “/” Empty lines read as zeros “0” entry in 10$ array not
permitted
