TAMBO Collaboration Meeting Summer 2026

.

As part of the development of the TAMBO-4 detector, the assembly of the panels provided by Harvard University was carried out. Data acquisition was performed using the RedPitaya platform, while data processing was conducted through a custom Python script. Initial tests were conducted under partial sealing conditions, which revealed a considerably high noise level. In response, a series of...

In this talk, I will give an overview of the different hardware components of TAMBITO.

In this talk, I will present the Harvard group's work on scintillator detector R&D, with a particular focus on different design approaches to identifying the MIP peak.

The uDAQ system is currently under evaluation as a potential data acquisition solution for the TAMBO-4 detector prototype. This presentation details several technical challenges faced during initial testing and the procedures implemented to address them. First, the limited baudrate of the uDAQ-lite restricts large data transmission, which was solved by establishing a safety limit to stop...

I will present preliminary laboratory measurements of the scintillation detectors using the uDAQs, along with some of the challenges encountered during these measurements.

The TAMBO project requires a communication system capable of reliably interconnecting a distributed network of detector nodes while satisfying demanding requirements in terms of data throughput, communication range, scalability, and energy consumption. The characteristics of the deployment environment and the expected number and distribution of nodes introduce additional challenges that must...

Some possible methods for reducing required communications bandwidth and overall power consumption of scintillator panels will be described.

I will give a brief update on the muon+muon neutrino background implementation into TAMBOSim, although final event rates are still pending large simulation runs. I'll also discuss the TAMBOSim parallelization work I've been doing to speed up high-energy simulated event generation.

At 6.3 PeV, the Glashow resonance ($\bar{\nu}_e + e^- \to W^- \to \tau^-\bar{\nu}_\tau$) feeds taus into TAMBO's detection channel, making a nominally $\nu_\tau$-only telescope sensitive to $\bar{\nu}_e$. This opens the door to flavor-composition measurements at the PeV scale and to a neutrino-versus-antineutrino measurement. But is this measurement actually feasible in practice? We assess the...

Earth-skimming tau neutrinos in the PeV–EeV range can be caught two ways. Radio antennas (GRAND) spread cheaply over thousands of square kilometers, as the rarest, most energetic events demand, and register the shower's electromagnetic component. Particle detectors packed across a canyon (TAMBO) cover far less ground, reach well below the radio threshold, and sample the full particle content....

The high energies and long distances travelled by astrophysical neutrinos make them an appealing probe of new physics, as exemplified by the many ways in which IceCube has been used to constrain scenarios. However, the need to distinguish a point source signal from many background events can limit the power of these tests. In this talk, I will outline ways in which TAMBO's very low background...

Musings on cosmic ray science we could (should) do with TAMBO/TAMBITO.

As a first step in characterizing the background, we studied proton-initiated showers on the TAMBO-4 prototype, whose initial deployment site is the PUCP campus in Lima. The simulation was carried out using TAMBOSim, and a brief discussion of the preliminary results is presented, contrasting them with the results obtained using only C8.

In this talk, Zigfried Hampel-Arias will present a brief career overview from cosmic ray physicist to remote sensing machine learning subject matter expert. First, he will present in depth on the HAWC Observatory, the resulting work from his PhD and postdoc tenures. Then he will describe the ongoing experimental results and validation from a career phase change to R&D in the interest of the...

Overview of simulation including recent changes, fixed bugs, and (hopefully) a full set of figures for the paper

Extensive air-shower simulations from primary cosmic rays are traditionally performed using computationally intensive Monte Carlo methods, consuming significant computational resources in astroparticle physics. To address this challenge, we propose a continuous normalizing flow matching model for the TAMBO experiment to accelerate shower simulations. Trained on high-energy showers generated...

As the TAMBO collaboration advances toward site selection and infrastructure planning, decision-making must integrate socioeconomic feasibility and long-term societal impact alongside detector physics performance. This presentation outlines the key contributions from Universidad del Pacífico across two core dimensions: regional socioeconomic mapping and formal Cost-Benefit Analysis (CBA) for...

In this talk, we will present an overview of the measurements made during the site visit along with our experience making these measurements in non-laboratory conditions.

Overview of the status of TAMBO-4 at PUCP.
