The molecule of the title compound, C6H12O6, [systematic name: (2R,3S,4R,5R,6R)-6-(hydroxymethyl)oxane-2,3,4,5-tetrol] adopts a 4
C
1 chair conformation with the anomeric hydroxyl group in the equatorial position. All hydroxyl groups act as donors and acceptors in hydrogen bonding and the molecule is involved in ten intermolecular O—H⋯O interactions [O⋯O = 2.672 (5)–2.776 (4) Å] with eight neighbouring molecules. Two independent O—H⋯O—H⋯ helices extending along the z axis are found in this structure
Conceptual Design of Rapid Circular Particle Accelerator Using High-Gradient Resonant Cavities with Fixed Frequency
A new high-energy particle accelerator with static combined type of magnetic field and high-gradient resonant cavities is introduced for muon acceleration up to 300 MeV and proton acceleration up to 400 MeV. The accelerator concept is expected to realize Mpps-class rapid cycling high-energy particle acceleration in circular particle accelerators. Conceptual designs of the circular accelerator are discussed with an emphasis on short lifetime particles. The fundamental concept of particle acceleration and the related practical issues, which should be discussed when designing the accelerators, are described as well
