IOTA_v2 Optim File

10/15/2013 05:59 PM

This lattice is mirror symmetric about the center of the injection leg/OSC channel. The injection is intended to coincide with the side containing 8 quadrupoles.

Added elements: space in the triplet section to suppress achromatic effects in OSC mode; magnetic edges for all sector dipoles; one additional dipole (39 total). Beamline-to-beamline height and width: 15.59m x 8.3m. ...

Beam Physics of IOTA at FNAL (FNAL APC 2012)

04/23/2013 10:41 AM

Fermilab's Integrable Optics Test Accelerator (IOTA) is an electron storage ring designed for testing advanced accelerator physics concepts, including implementation of nonlinear integrable beam optics and experiments on optical stochastic cooling. The machine is currently under construction at the Advanced Superconducting Test Accelerator facility. In this report we present the goals and the current status of the project, and describe the details of machine design. In particular, we concentrate on numerical simulations setting the requirements on the design and supporting the choice of machine parameters....

IOTA OptiM file

09/05/2013 04:13 PM

This file contains the geometry for the IOTA ring (38 quads) with hall constraints taken into account. The lattice starts at the middle of the IO section and repeats itself at the middle of the second IO section.

IO sections are 1.8 m.
OSC channel (wigglers and chicane)is 422.25 m. There will be an additional space for 2 quads and a bpm on either end (619.75 m total); valves will be included between the dipoles and quads.

IOTA Lattice V6.6

10/22/2014 08:52 PM

The latest mad-x lattice with 4 configurations:
  1. 1 Integrable Optics section
  2. 2 IO sections
  3. Electron Lens

IOTA_v6.5 MADX file with 4 quadrupole configuration files

06/05/2014 02:30 PM

New version UPDATE: includes the electron lens configuration. The electron lens will be located inside the 70cm solenoid in one of the short drift sections. There are also 4 additional quadrupole circuits added for this configuration.

Each configuration (OSC, 1 and 2 nonlinear sections, and electron lens) now comes with a separate configuration file in which each section of the ring is described.

IOTA_v6 MADX file with 3 configurations

10/02/2014 04:15 PM

This file contains the quadrupole gradients for the 3 following configurations of the IOTA lattice:

1. OSC
2. 1 integrable optics insert (tunes: Qx=5.3, Qy=5.3)
3. 2 integrable optics inserts (tunes: Qx=5.1, Qy=5.1)

The configurations are specified at the top the the file. Set "loption" to 0, 1 or 2 for OSC, 1-IO or 2-IOs....

Git repository for IOTA lattices

06/15/2016 02:34 PM

I updated IOTA lattices v8.3 in our git repository. To get it you need to run something like:

git clone ssh:///cvs/projects/iota-lattice

It has all lattices in in formats of MADX, 6dsimulation and also OSC for OptiM.

RF Capture of Protons in the IOTA Ring

01/22/2015 12:27 PM

This document discusses the RF Capture of 2.5 MeV proton beam into the IOTA ring at Fermilab. Two RF systems are considered: $h$=4 (2.19 MHz) and $h$=56 (30.62 MHz).
It is found that we will be able to fully bunch the inejcted beam with 1 kV or less of voltage on the $h$=4 system. The 1kV limit of the $h$=56 system will not be
