Sapucaia\u00a0and\u00a0Quati: new\u00a0beamlines\u00a0open for\u00a0proposals<\/span>\u00a0<\/span><\/h3>\n

In this call, the Sapucaia and Quati beamlines will be available for proposal submission for the first time. Both beamlines have undergone commissioning periods, including technical adjustments and testing of their installations, and are now joining the set of beamlines open to users.<\/span>\u00a0<\/span><\/p>\n

SAPUCAIA (Scattering APparatUs for Complex Applications and In situ Assays) is dedicated to small-angle X-ray scattering (SAXS) and ultra-small-angle X-ray scattering (USAXS) techniques. These structural characterization methods are widely used to study morphological properties such asshape, size, distribution, and spatial organization of nano- and microstructured systems. In addition, these techniques enable time-resolved kinetic studies with temporal resolution on the order of milliseconds.<\/span>\u00a0<\/span><\/p>\n

The beamline allows users to investigate relevant problems in the life sciences, with biological and medical applications, structural biology \u2014 including proteins nucleic acids, lipids, and macromolecules in general \u2014 as well as multiple topics in materials science, such as nanotechnology, polymers, and environmental sciences.<\/span>\u00a0<\/span><\/p>\n

The QUATI\u00a0beamline (Quick X-ray Absorption Spectroscopy for Time- and Space-Resolved Experiments) is dedicated to X-ray absorption spectroscopy (XAS) experiments with high temporal and spatial resolution. The station provides XANES and EXAFS measurements in the 4.5\u201335 keV energy range, covering K-edges from titanium to xenon, as well as elements with L-edges.<\/span>\u00a0<\/span><\/p>\n

With a variable beam size, Quati enables structural studies under insitu\/operando conditions, including high temperatures, gas flow, or pressure, supporting applications in catalysis, materials science, nanotechnology, environmental sciences, and life sciences.<\/span>\u00a0<\/span><\/p>\n

Updates\u00a0to\u00a0the\u00a0proposal\u00a0submission\u00a0form<\/span><\/b>\u00a0<\/span><\/h3>\n

Starting with this call, the proposal submission form has been updated to make the scientific evaluation process clearer and more efficient, while also optimizing the use of the beamlines. The changes encourage more concise and objective texts, with well-defined hypotheses and consistent descriptions of the proposed experiment.<\/span>\u00a0<\/span><\/p>\n

The new model emphasizes clarity, adherence to the scientific method, and detailed descriptions of prior characterizations supporting the feasibility of the study. The goal is to\u00a0facilitate\u00a0the identification of the study\u2019s central idea and the maturity level of the proposed experiment.<\/span>\u00a0<\/span><\/p>\n

\u201cThese updates are part of a continuous improvement process built through dialogue with the Sirius user community. The\u00a0objective\u00a0is to make submission and evaluation clearer and more efficient, valuing more objective and well-founded proposals and contributing to better use of the beamlines,\u201d says LNLS Director\u00a0Harry Westfahl Jr.<\/span>\u00a0<\/span><\/p>\n

With these changes, LNLS aims to make the evaluation process more agile, transparent, and aligned with best practices, reducing\u00a0ambiguities\u00a0and increasing the overall quality of\u00a0submitted\u00a0proposals.<\/span>\u00a0<\/span><\/p>\n

Early submission increases chances of technical suitability<\/span><\/b>\u00a0<\/span><\/h3>\n

In addition to changes to the proposal format, the technical feasibility evaluation process will also be\u00a0modified, becoming more active, continuous, and integrated into the submission workflow.<\/span>\u00a0<\/span><\/p>\n

The analysis will begin as soon as a proposal is\u00a0submitted, without the need to wait until the final deadline of the call (March 8). Beamline scientists will provide feedback as soon as possible, allowing proponents to clarify experimental aspects and, when\u00a0feasible, adjust the proposal to the beamline\u2019s capabilities.<\/span>\u00a0<\/span><\/p>\n

After March 8, the system will remain open only for technical adjustments requested during the feasibility evaluation stage conducted by the beamline coordinators. Evaluations will take place until March 22, and early submission offers\u00a0additional\u00a0time for revisions and potential technical adjustments.<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

Available beamlines<\/span><\/b>\u00a0<\/span><\/h3>\n

Ten beamlines are enabled to receive research proposals in this call. The\u00a0Manac\u00e1\u00a0and Cedro beamlines continue to receive proposals on a continuous basis through the Fast Track\u00a0modality, meaning these beamlines\u00a0remain\u00a0open for proposal submission without interruption.<\/span>\u00a0<\/span><\/p>\n

The beamlines receiving proposals in this cycle are:<\/span>\u00a0<\/span><\/p>\n

Carna\u00faba<\/strong>: Micro- and nano-scale X-ray fluorescence, X-ray spectroscopy, and ptychographic imaging<\/span>\u00a0<\/span><\/p>\n

Cateret\u00ea<\/strong>: Coherent diffraction imaging (ptychography) and X-ray photon correlation spectroscopy (XPCS)<\/span>\u00a0<\/span><\/p>\n

Ema<\/strong>: X-ray diffraction and spectroscopy under extreme conditions of pressure, temperature, and magnetic field<\/span>\u00a0<\/span><\/p>\n

Imbuia<\/strong>: Infrared\u00a0nanospectroscopy\u00a0(nano-FTIR)<\/span>\u00a0<\/span><\/p>\n

Mogno<\/strong>: Micro- and nano-scale X-ray tomography<\/span>\u00a0<\/span><\/p>\n

Paineira<\/strong>: Powder X-ray diffraction (PXRD)<\/span>\u00a0<\/span><\/p>\n

Cedro<\/strong>: Electronic circular dichroism (CD) spectroscopy in the ultraviolet (UV) region<\/span>\u00a0<\/span><\/p>\n

Manac\u00e1<\/strong>: Macromolecular\u00a0microcrystallography\u00a0(MX)<\/span>\u00a0<\/span><\/p>\n

Sapucaia<\/strong>: Small-angle X-ray scattering (SAXS) and ultra-small-angle X-ray scattering (USAXS)<\/span>\u00a0<\/span><\/p>\n

Quati<\/strong>: X-ray absorption spectroscopy (XAS) with high temporal and spatial resolution<\/span>\u00a0<\/span><\/p>\n

During this call, the\u00a0Ip\u00ea\u00a0beamline will undergo an upgrade with the installation of a new undulator, expected to increase the photon flux by approximately one order of magnitude and enable vertical and circular polarization. These improvements will allow RIXS experiments to be carried out with higher resolution and under new experimental conditions. After installation, the beamline will go through a commissioning period and is expected to be ready to receive proposals in early 2027.<\/span>\u00a0<\/span><\/p>\n

The\u00a0Sabi\u00e1\u00a0beamline will be dedicated to previously scheduled experiments and is expected to open for new proposal submissions in the next Sirius call.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span>Evaluation process<\/span><\/b>\u00a0<\/span><\/h3>\n

Proposals will be evaluated through a distributed double-blind peer-review process, in which the Principal Investigators (PIs)\u00a0submitting\u00a0proposals also act as reviewers of other proposals from the community. Each\u00a0submitted\u00a0proposal is evaluated by at least five reviewers, and each PI\u00a0is required to\u00a0review five proposals, regardless of whether they are new submissions or resubmissions.<\/span>\u00a0<\/span><\/p>\n

The quality of the reviews is\u00a0taken into account\u00a0in the final proposal score. Superficial or missing technical comments will result in penalties. Evaluation guidelines are available on the LNLS Users\u2019 Page.<\/span>\u00a0<\/span><\/p>\n

Proposal resubmission<\/span><\/b>\u00a0<\/span><\/h3>\n

As in\u00a0previous\u00a0calls, well-evaluated proposals that were not awarded beamtime in the\u00a0previous\u00a0call may be resubmitted in this edition, with an automatic increase of 0.2 points\u00a0added to the original score. To qualify, the\u00a0proposal\u00a0content must remain unchanged. If the proponent wishes to update the text, a new standard submission is\u00a0required.<\/span>\u00a0<\/span><\/p>\n

The resubmission functionality is available on the SAU Online platform. Resubmitted proposals also require the submission of five ad hoc reviews\u00a0by the Principal Investigator (PI), as in standard submissions.<\/span>\u00a0<\/span>\u00a0<\/span><\/p>\n

Beamlines under commissioning<\/span><\/b>\u00a0<\/span><\/h3>\n

Although not yet included in this regular call, the\u00a0Sap\u00ea\u00a0and Tatu beamlines \u2014 dedicated to angle-resolved photoemission spectroscopy (ARPES) and terahertz\u00a0nanospectroscopy, respectively \u2014 are currently in the commissioning phase. Experiments supporting the final adjustments of these stations are scheduled throughout 2026, with the participation of invited users. These beamlines will be available for regular submissions in future calls.<\/span>\u00a0<\/span><\/p>\n
